Iron-catalyzed microwave-promoted expeditious one-pot synthesis of benzo[b][1,4]thiazine-4-carbonitrile under solvent-free condition

A highly efficient one pot green synthesis of benzo[b][1,4]thiazine-4-carbonitrile has been achieved under solvent-free conditions by the reaction of 2-aminobenzothiazole with terminal alkynes using microwave irradiation in the presence of Iron(III)fluoride as a catalyst. The unique features of this environmentally benign protocol are use of inexpensive catalyst, short reaction time, a wide range of functional group tolerance, easy and quick isolation of products with good to excellent yields via a simple experimental and work-up procedure. The catalyst can be recovered and reused for at least three runs without any significant impact on product yields. (C) 2016 Elsevier Ltd. All rights reserved.

Tunable Synthesis of Disulfide-Functionalized Enaminones and 1,4-Thiazines via the Reactions of Enaminones and ss-Aminoethanethiol

The reactions of ss-aminoethanethiol with N, N-dimethyl enaminones are performed to selectively provide disulfide-functionalized enaminones and 1,4-thiazines. By performing the reaction in water and catalyst-free conditions, the transamination and oxidative S-S coupling between the two substrates take place to give disulfide-functionalized enaminones. On the other hand, by using identical starting materials, the employment of the CuI catalyst in dimethyl sulfoxide enables the selective generation of 1,4-thiazines via tandem transamination and C(sp(2))-H bond thiolation.

The metal complexes exhibited square planar, tetrahedral and octahedral geometrical arrangements, the molar conductivity data indicates that all complexes are neutral. The Coats-Redfern equation was used to calculate the kinetic and thermodynamic parameters for the different thermal decomposition stages of some complexes. Structural parameters of the ligand and its metal complexes have been theoretically computed on the basis of semiempirical PM3 level and the results were correlated with their experimental data. Antibacterial activities of the free ligand and its metal complexes were screened against various organisms. (C) 2014 Elsevier B.V. All rights reserved.

A three-component reaction for rapid access to underexplored 1,3-thiazine-2-thiones

Driven by the shortage of known effective possibilities for the synthesis of 4-hydroxy-3,4-dihydro-2H-1,3-thiazine-2-thiones on the one hand and the promising potential of these structures as novel drug candidates on the other hand, synthetic access to 4-hydroxy-3,4-dihydro-2H-1,3-thiazine-2-thiones was developed. The desired products could be synthesized effectively and facilely starting from beta-chlorovinyl aldehydes with the aid of a new MCR (multicomponent reaction).

Additive-induced aggregate changes of two structurally similar dyes in aqueous solutions: A comparative photophysical study

Absorption and emission spectral characteristics of the two structurally similar phenothiazine dyes, azure B and toluidine blue, in aqueous solutions of the two sets of molecular additives (ureas and monosaccharides) were studied as a function of the dye and additive concentrations. The absorption spectra of the dyes were also studied in pure tetramethylurea with an aprotic nature. The spectral data were analyzed using DECOM Program. The dimer structure of the interacting molecules in these dyes was discussed using the exciton model. The urea class of additives was found to act as water structure-breakers over the range of studied concentration. The carbohydrate additives were found to act as water structure-breakers at low concentrations. However, the water structure breaking process may be disfavored by the additive-additive interactions at higher concentrations. It can be concluded that at low additive concentrations, the main driving force for breaking the dye association is water-additive interaction, which disrupts the water hydrogen bonds induced by the additives. However, at the high additive concentrations, the different phenomena including additive-additive and additive-dye interactions can change the structure, strength, and aggregative properties of the dyes. Finally, the urea in water induces noticeably fluorescence quenching in emission spectra of both the dyes. (C) 2017 Elsevier B.V. All rights reserved.

This review’s main motive is to present the literature on 2-acetylbenzimidazole chemistry and provide valuable and up-to-date information for its applications. The present review is carried out by compiling literature from 1964 to 2020 concerning the synthesis and biological aspects of various heterocyclic compounds derived from 2-acetylbenzimidazole. Literature was collected from various online search engines viz. Google Scholar, PubMed, Science Direct, Core, and Semantic scholar. 2-acetylbenzimidazole has been successfully employed as a synthon to obtain heterocyclic system viz. oxirane, pyrazoline, thiazole, pyrazole, isoxazoline, isoxazole, pyridine, pyrimidine, thiazine, diazepine, and other miscellaneous rings. 2-acetylbenzimidazole has shown promise for the convenient synthesis of various heterocyclic compounds. The reactions can be carried out on various reactive sites of 2-acetylbenzimidazole, which are the carbonyl group and the amino group. This review will help to explore various heterocyclic compounds and particularly in the synthesis of biologically useful compounds.

Selected azaphenothiazines inhibit delayed type hypersensitivity and carrageenan reaction in mice

Several, previously selected azaphenothiazines, as strongly antiproliferative agents in in vitro models, were subjected to evaluation for their potential immunosuppressive effects in the model of delayed type hypersensitivity (DTH) to ovalbumin (OVA) in BALB/c mice and in foot pad inflammation induced by carrageenan in CBA mice. In the DTH model the compounds were given to mice intraperitoneally (i.p.) in 50 mu g or 250 mu g doses, 1 h before the elicitation of the response. In the carrageenan-induced foot pad inflammation the compounds were given i.p. in 50 mu g or 250 mu g doses, 24 h and 2 h before administration of carrageenan. Among the compounds, the significantly suppressive activities in both models were exhibited only by compound 5 (6-chloroethylureidoethyldiquino[3,2-b;2′,3′-e][1,4]thiazine) and compound 4 (6-acetylaminobuty1-9-chloroquino[3,2-blbenzo[1,4]thiazine). Structure-activity relationship, plausible mechanism of action and potential application in therapy of the compounds are discussed. (C) 2016 Elsevier B.V. All rights reserved.
