The first observation on polymerization of 1,3-benzothiazines: synthesis of mono- and bis-thiazine monomers and thermal properties of their polymers

A monofunctional 1,3-benzothiazine (PH-a-BZT) has been synthesized by a method different from the one reported in the literature. Additionally, a difunctional version of 1,3-benzothiazine (PH-ddm-BZT) monomer has been synthesized. Polymerization of mono- and bis-thiazine monomers has been studied and confirmed for the first time. The two monomers are characterized with proton and carbon nuclear magnetic resonance spectroscopy (H-1-NMR, C-13-NMR) along with Fourier transform infrared (FT-IR) spectroscopy. The cross-linked polybenzothiazine which is derived from the bis-thiazine monomer shows excellent thermal properties as examined by thermogravimetric analysis (TGA). Polybenzothiazine is developed in hopes that it could mimic many of benzoxazine’s popular attributes while containing sulfur in place of oxygen atoms. It can also possess unique advantages such as higher flame retardancy and adhesiveness to the metal substrate than polybenzoxazine due to the characteristic sulfur atom in its polymer.

Experimental and Theoretical Studies of the Corrosion Inhibition of 4-amino-2-(4-chlorophenyl)-8-(2, 3-dimethoxyphenyl)-6-oxo-2, 6-dihydropyrimido [2, 1-b][1, 3] thiazine-3,7-dicarbonitrile on Carbon Steel in a 1.0 M HCl Solution

The corrosion inhibition of carbon steel in a 1.0 M HCl solution, using 4-amino-2-(4-chlorophenyl)-8-(2,3-dimethoxyphenyl)-6-oxo-2,6-dihydropyrimido[2, 1b][1,3] thiazine-3,7-dicarbonitrile (ACMPT) was investigated by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and quantum chemical calculations. Polarization curves indicate that the studied compound was acting as a mixed inhibitor with predominant cathodic effectiveness. The inhibition efficiency decreased with an increased temperature, and the thermodynamic and activation parameters obtained from this study were discussed. The adsorption behavior of ACMT follows Langmuir’s isotherm. In addition, Density Function Theory (DFT) calculations were performed on the studied molecule. The theoretical parameters obtained from this method are in good agreement with the experimental results.

An operational study comparing microscopes and staining variations for tuberculosis LED FM

SETTING: Tuberculosis control projects, Damien Foundation Bangladesh. OBJECTIVES: To compare transmitted fluorescence (Olympus CX21 (TM)/FRAEN FluoLED (TM)) with epi-fluorescence (Zeiss Primostar iLED (TM)) light-emitting diode microscopes (LED-FM) and various auramine staining and destaining/counterstaining techniques for the detection of acid-fast bacilli. DESIGN: Multicentre blinded reading of routine smears on both types of microscopes using different staining techniques in multiple phases. LED-FM rechecking of discordant series with and without restaining to calculate operating characteristics. RESULTS: Among 64 874 smears, both instruments detected 9.6% positives. Compared to the standard technique, the stronger auramine-O formulation did not perform better. Thiazine red counterstaining tended to yield more false-positive as well as false-negative errors. Combined destaining/counterstaining (sensitivity 93%, positive predictive value [PPV] 98%) proved significantly less effective. Both destaining with 1% hydrochloric acid (HCl) and 10% alcohol and the standard 0.5% HCl and 70-95% alcohol were equally accurate (sensitivity 95-96%, PPV 99%). The sturdiness of the microscopes in field conditions was sub-optimal: only 5/16 instruments did not break down. CONCLUSIONS: Both microscopes performed equally well. The standard staining technique is as good as the more complicated and expensive variations. A destaining solution containing only 10% alcohol works perfectly well. The inferior quality of LED-FM microscope components is an obstacle to FM expansion.

Synthesis of New Derivatives of Heterocyclic Systems Containing Triazolopyrimidine, thiazolo[3,2-a]pyrimidine and pyrimido[2,1-b] thiazine Moiety Showing Promising Antimicrobial Activity

Background and Objective: Continuing our research in the field of heterocyclic compounds and exploiting our experience in the synthesis of pyridothieno(furo)[3,2-d]pyrimidine derivatives decorated by suitable reactive groups (in turn able to give rise to the formation of new heterocyclic rings), we now carried out a research with the aim of building in different position of the pyrimidine some new hetero-rings: the 1,3,4-triazole, thiazole and thiazine. Moreover their possible antimicrobial activity against some gram-positive and gram-negative bacilli strains has been evaluated. Methods: Starting from the hydrazino derivative of pyrido[3′,2′:4,5]thieno(furo)[3,2-d]pyrimidines 2 (7) by reflux with triethyl orthoformate or formic acid, some substituted isomeric pyrido[3′,2′:4,5]thieno(furo)[2,3-e][1,2,4]triazolopyrimidines 3 and 4 (10) have been synthesized. By alkylation of compounds 8 with alkyl dichlorides, the cyclization to a thiazoline or to a thiazine ring on the [a] side of the pyrimidine ring occurs, with the formation of the new pentacyclic systems: pyrido[3′,2′:4,5]thieno[3,2-d][1,3]thiazolo[3,2-a]pyrimidin-7(8)-one 15 and pyrido[3 ”,2 ”:4′,5′]furo(thieno)[3′,2′:4,5]pyrimido[2,1-b][1,3]thiazin-7(8)-ones 16. Results: 11-Alkyl(aryl)-8,8-dimethyl-7,10-dihydro-8H-pyrano[4 ”,3 ”:4′,]pyrido[3′,2′:4,5]thieno[2,3-e][1,2,4] triazolo[4,3-c]pyrimidines 3 gave a Dimroth rearrangement in acidic media. It was observed that the cyclization of compounds 7 and 8 occurred linearly with the expected formation of pyrido[3′,2′:4,5]thieno(furo)[3,2-d][1,2,4]triazolo[4,3-a]pyrimidin-7(8)-ones 10 and pyrido[3′,2′:4,5]thieno[3,2-d][1,3]thiazolo[3,2-a]pyrimidin-7(8)-one 15 and pyrido[3 ”,2 ”:4′,5′]furo(thieno)[3′,2′:4,5]pyrimido[2,1-b][1,3]thiazin-7(8)-ones 16: that is triazole, thiazole and thiazine ring condensation occurs at the [b] side of the pyrimidine ring. During the alkylation of compounds 7, the unusual cleavage of the hydrazino group took place with the formation of 8(9)-methylpyrido[3′,2′:4,5]thieno(furo)[3,2-d]pyrimidin-7(8)-ones 12. Conclusion: The synthesis of some new ‘complex’ pentaheterocyclic systems containing triazolopyrimidine, thiazolo[3,2-a]pyrimidine and pyrimido[2,1-b]thiazine moiety based on the pyrido[3′,2′:4,5]thieno(furo)[3,2-d]pyrimidines is described. During the alkylation of 9(10)-hydrazinopyrido[3′,2′:4,5]thieno(furo)[3,2-d]pyrimidin-7(8)-ones 7 an unexpected cleavage of the hydrazino group has been observed with the formation of 8(9)-methylpyrido[3′,2′:4,5]thieno(furo)[3,2-d]pyrimidin-7(8)-ones 12. Biological tests on the newly synthesized compounds evidenced that some of them showed promising antimicrobial activity.

Crystal structure of rac-2,3-diphenyl-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-one 1-oxide

In the title compound, C(16)Hi(5)NO(2)S [alternative name: rac-2,3-diphenyl-1,3-thiazinan-4-one 1-oxide], the thiazine ring exhibits an envelope conformation, with the S atom forming the flap. The sulfoxide 0 atom is in a pseudo-axial position on the thiazine ring and is trans to the phenyl group on C-2. The phenyl rings form a dihedral angle of 89.47 (19)degrees. In this racemate crystal, homochiral molecules form slabs parallel to (010) of thickness b/2 which then stack with alternating chirality in the b-axis direction. The stacking is aided by edge-to-face interactions between the phenyl rings of racemic molecules. Within each of the single-enantiomer slabs, the molecules are held by C-H center dot center dot center dot O-type interactions, with an H center dot center dot center dot O distance of 2.30 angstrom, forming infinite chains along the c-axis direction, as well by the edge-to-face interactions between phenyl rings of neighboring molecules in the a-axis direction.

5H-Benzo[d]Benzo[4,5]Imidazo[2,1-b][1,3]Thiazine as a Novel Electron-Acceptor Cored High Triplet Energy Bipolar Host Material for Efficient Solution-Processable Thermally Activated Delayed Fluorescence Organic Light-Emitting Diodes

Organic entities that can transport electrons are seldom available to develop adequate bipolar host materials applicable for solution-processable thermally activated delayed fluorescence (TADF)-organic light-emitting diodes (OLEDs). Therefore, the introduction of new electron-affine entities that plausibly demonstrate high triplet energy (E-T) is of urgent need. In this contribution, we introduced benzimidazo[1,2-a][3,1]benzothiazine (BBIT) as a novel electron-affine entity and developed two new bipolar host materials, CzBBIT and 2CzBBIT. Both host materials exhibit high E-T of 3.0 eV, superior thermal robustness with the thermal decomposition temperature of up to 392 degrees C, a glass transition temperature of up to 161 degrees C, and high solubility in common organic solvents. Consequently, the solution-processable OLEDs fabricated using a recognized IAcTr-out as the green TADF emitter doped into CzBBIT as the host, realized a maximum external quantum efficiency (EQE) of 23.3%, while the 2CzBBIT:IAcTr-out blend film-based device displayed an EQE of 18.7%. These outcomes corroborated that this work could shed light on the scientific community on the design of new electron-affine entities to establish the effective use of bipolar host materials toward proficient solution-processable TADF-OLEDs.

Azide based routes to tetrazolo and oxadiazolo derivatives of pyrrolobenzodiazepines and pyrrolobenzothiadiazepines

Tetrazolo- and 1,2,4-oxadiazolo-fused derivatives of the antitumour, antibiotic, DNA-interactive pyrrolo [2,1-c][1,4]benzodiazepines and their pyrrolobenzothiadiazepine derivatives have been produced as analogues of a 1,2,3-triazolo-fused pyrrolobenzothiadiazepine, which was shown to be a Glut-1 transporter inhibitor with potential as an antitumour agent. The tetrazolo-fused systems were produced by intramolecular 1,3-dipolar cycloaddition between an azide and a nitrile. The 1,2,4-oxadiazolo systems were produced by nitrile oxide cycloadditions to pyrrolobenzothiadiazepines, which were in turn produced from a 2-(azidobenzenesulfonyl)-1,2-thiazine 1-oxide. The latter species underwent a phosphite-mediated one-pot sulfur-extrusion, ring-contraction and azide to amine conversion to form 1-(amino-benzenesulfonyl)pyrroles. Bischler-Napieralski ring closure gave the pyrrolobenzothiadiazepines. (C) 2014 Elsevier Ltd. All rights reserved.

Crystal structure, Hirshfeld surface analysis, interaction energy and DFT studies of (2Z)-2-(2,4-dichlorobenzylidene)-4-nonyl-3,4-dihydro-2H-1,4-benzothiazin-3-one

The title compound, C24H27Cl2NOS, contains 1,4-benzothiazine and 2,4-dichlorophenylmethylidene units in which the dihydrothiazine ring adopts a screw-boat conformation. In the crystal, intermolecular C-H-Bnz center dot center dot center dot O-Thz (Bnz = benzene and Thz = thiazine) hydrogen bonds form chains of molecules extending along the a-axis direction, which are connected to their inversion-related counterparts by C-H-Bnz center dot center dot center dot Cl-Dchlphy (Dchlphy = 2,4-dichlorophenyl) hydrogen bonds and C-H-Dchlphy center dot center dot center dot pi(ring) interactions. These double chains are further linked by C-H-Dchlphy center dot center dot center dot O-Thz hydrogen bonds, forming stepped layers approximately parallel to (012). The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H center dot center dot center dot H (44.7%), C center dot center dot center dot H/H center dot center dot center dot C (23.7%), Cl center dot center dot center dot H/H center dot center dot center dot Cl (18.9%), O center dot center dot center dot H/H center dot center dot center dot O (5.0%) and S center dot center dot center dot H/H center dot center dot center dot S (4.8%) interactions. Hydrogen-bonding and van der Waals interactions are the dominant interactions in the crystal packing. Computational chemistry indicates that in the crystal, C-H-Dchlphy center dot center dot center dot OThz, C-H-Bnz center dot center dot center dot O-Thz and C-H-Bnz center dot center dot center dot Cl-Dchlphy hydrogen-bond energies are 134.3, 71.2 and 34.4 kJ mol(-1), respectively. Density functional theory (DFT) optimized structures at the B3LYP/6-311 G(d,p) level are compared with the experimentally determined molecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap. The two carbon atoms at the end of the nonyl chain are disordered in a 0.562 (4)/0.438 (4) ratio.
