Utilizing Amines and Carbon Disulfide to Obtain Nitrogen- and Sulfur-containing Compounds under Green Conditions: A Review

As multi-component reactions have been among the most important and advantageous methodologies in organic chemistry since 150 years ago, the present review focuses on one-pot multi-component reactions containing amines and carbon disulfide as constant starting materials along with other essential substances to afford the corresponding nitrogen-and sulfur-containing products in demand such as thiazolidine-2-thiones, 2-imino-1,3-dithiolanes, 2-substituted benzothiazoles, 1,3-thiazine-2-thiones, dithiocarbamate derivatives, and thioureas through green methodologies. This synthetic field has been widely studied throughout the last two decades to achieve such biologically active structures. The progress orientation of these reports towards green chemistry principles is reviewed from 2000 to December 2017.

Dual catalysis system for ring-opening polymerization of lactones and 2,2-dimethyltrimethylene carbonate

In this study, three isothioureas (ITUs), 2,3,5,6-tetrahydroimidazo[2,1-b]thiazole (ITU 1), 2,3,6,7-tetrahydro-5H-thiazolo-[3,2-a]pyrimidine (ITU 2) and 3,4,7,8-tetrahydro-2H,6H-pyrimido[2,1-b][1,3]thiazine (ITU 3) were prepared. These ITUs coupled with magnesium halides (MgX2) as the cocatalysts, cooperatively promoted the ring-opening polymerization (ROP) of several common lactones (including -valerolactone, epsilon-caprolactone, epsilon-decalactone and even of macrolactone -pentadecalactone) and 2,2-dimethyltrimethylene carbonate. These cocatalysts were found to exhibit suitable activities and ITU 2 emerged as the most active organic component. The order of activities for the magnesium halides was found to be lying in the following order: MgI2 > MgBr2 > MgCl2. The polymerizations attained high conversions (>90%) under optimal conditions, and produced linear polyesters having predictable molecular weights, narrow polydispersity indices (PDIs < 1.20) and defined end groups, which were derived from the benzyl alcohol initiator. The resulting polymers were characterized using GPC, IR, DSC, NMR and MALDI-ToF mass. The kinetic and chain extension experiments showed that the ITUs/MgX2-cocatalyzed ROPs of epsilon-caprolactone proceeded a living polymerization characteristics. Furthermore, the proposed polymerization mechanism was supposed to be a dual catalytic mechanism, and involved the activation of monomers through coordination to Lewis acids, while the initiator was activated by bases. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.

An efficient ligand-free ferric chloride catalyzed synthesis of annulated 1,4-thiazine-3-one derivatives

A straight forward route for the synthesis of coumarin-, quinolone-annulated 1,4-thiazine-3-one derivatives has been achieved by using sodium sulfide as the sulfur source and ferric chloride as catalyst in a ligand-free condition. The synthetic procedure is simple, inexpensive, and affords the products in good yields. This methodology is also applicable to naphthalene and benzene systems. (C) 2014 Elsevier Ltd.

Novel series of dihydroquinolindihydro-spiro[indoline-3,6 ‘-[1,3]thiazine]-5 ‘-carbonitrile derivatives

A series of new spiro[indoline-3,6’-[1,3]thiazines] were synthesized in modest yields by refluxing of substituted (1,2-dihydroquinolin-3-yl)-methylene)hydrazinecarbothioamides with 2-(2-oxoindolin-3-ylidene)malononitrile in pyridine as a solvent. The structure assignment of all obtained products has been confirmed by H-1, C-13 NMR, 2D-NMR, N-15 NMR spectroscopy in addition to elemental analyses. The possible mechanism for the reaction is also discussed. (C) 2020 Published by Elsevier B.V.

Facile, Odourless, Quantitative Synthesis of 3-Hydroxy-3,4-dihydro-2H-1,4-thiazines

A sulfa-Michael addition/formal [3+3] annulation cascade reaction between 1,4-dithiane-2,5-diol and 1,2-diaza-1,3-dienes by a one-pot base-catalysed strategy was developed. This metal-free and odourless method provides a practical and facile approach to 1,4-thiazines obtained in total atom economy and in quantitative yields. Furthermore, the synthesis could be scaled-up to the gram scale.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 151-21-3, in my other articles. Category: thiazines.

Crystal structure of (1S, 2S, 5R)-5-acetylamino-4oxo-2,3-diphenyl-1,3-thiazinan-1-ium-1-olate

The asymmetric unit of the enantiomerically pure title compound, C18H18N2O3S, comprises two independent molecules (A and B) having almost identical conformations. When overlayed, the alignment-r. m. s. deviation value is 0.30 angstrom. The six-membered heterocycle has a twisted half-chair conformation in both molecules. The O atom on the S atom of the ring is pseudo-axial on the thiazine ring and trans to both a phenyl group substituent and the acetamide group in each case. The two benzene rings in each molecule are almost orthogonal to each other, with interplanar dihedral angles of 83.79 (17) and 86.95 (16)degrees. The acetamide group is pseudo-equatorial and a phenyl ring is pseudo-axial on the thiazine ring. Both molecules show a weak intramolecular C-H center dot center dot center dot O interaction between H-atom donors of one of the phenyl rings and the acetamide group. In the crystal, an intermolecular N-H center dot center dot center dot O( thiazine) hydrogen bond links B molecules along the 21 (b) screw axis and, in addition, an N-H center dot center dot center dot O( acetamide) hydrogen bond links A and B molecules across a. A two-dimensional layered structure lying parallel to (001) is generated, also involving weak intermolecular C-H center dot center dot center dot O interactions.

Stereoselective Synthesis and Cytoselective Toxicity of Monoterpene-Fused 2-Imino-1,3-thiazines

Starting from pinane-, apopinane- and carane-based 1,3-amino alcohols obtained from monoterpene-based beta-amino acids, a library of monoterpene-fused 2-imino-1,3-thiazines as main products and 2-thioxo-1,3-oxazines as side-products were prepared via two-or three-step syntheses. When thiourea adducts prepared from 1,3-amino alcohols and aryl isothiocyanates were reacted with CDI under mild conditions, O-imidazolylcarbonyl intermediates were isolated which could be transformed to the desired 1,3-thiazines under microwave conditions. 1,3-Thiazines and 2-thioxo-1,3-oxazine side-products could also be prepared in one-step reactions through the application of CDI and microwave irradiation. The ring-closure process was extended to cycloalkane-based gamma-hydroxythioureas. The carane-and apopinane-based derivatives exhibited marked antiproliferative activity against a panel of human adherent cancer cell lines (HeLa, A2780, MCF7 and A431).

Lipophilicity estimation of anti-proliferative and anti-inflammatory 6-substituted 9-fluoroquino[3,2-b]benzo[1,4]thiazines

The lipophilicity parameters (logP(calcd), R-M0 and logP(TLC)) of 17 new anti-proliferative and anti-inflammatory tetracyclic 6-substituted 9-fluoroquinobenzothiazines were determined theoretically using computational methods and experimentally by reversed-phase thin-layer chromatography. The experimental parameter R-M0 was determined on the RP-18 silica plates with acetone-aqueous TRIS buffer as mobile phase. The obtained parameter R-M0 was further transformed into parameter logP(TLC) by use of the calibration curve. The theoretical logP(calcd) values differed depending on the substituents and nature of calculating programs. Fluoroquinobenzothiazines turned out to be rather middling or highly lipophilic compounds. The parameter R-M0 and specific hydrophobic surface area b were meaningly intercorrelated showing congeneric two classes of quinobenzothiazines. The calculated logP(calcd) and experimental logP(TLC) values were compared and intercorrelated to show different prediction power of the computational programs. The lipophilicity was correlated with molecular descriptors (molar mass, molar volume, and molar refractivity), biomolecular descriptors (HIA, PB, MDCK, Caco-2, and BBB) and in vitro tested biological activities (tumor necrosis factor alpha inhibition and antiproliferative activity).
