Access to SCN-containing thiazolines via electrochemical regioselective thiocyanothiocyclization of N-allylthioamides

An electrochemical thiocyanothiocyclization of N-allylthioamides has been developed for the synthesis of SCN-containing 2-thiazolines. This method provides a green and efficient approach to generate 5-exo-cyclization 2-thiazolines with a broad substrate scope and good yields. In addition, 6-endo-cyclization isothiocyanato thiazines are formed regioselectively when cyclic thioamides are used as reactants. The reaction is easy to proceed under catalyst-, additive- and oxidant-free conditions.

The Smiles rearrangement in the syntheses of azaphenothiazines. Part II. The review of the various types of phenyl azinyl and diazinyl sulfides undergoing this rearrangement

Azaphenothiazines are one of the most bioactive heterocyclic scaffolds in medicinal chemistry. This review discusses the Smiles rearrangement of over 40 types of phenyl azinyl sulfides and diazinyl sulfides during syntheses of azaphenothiazines. These syntheses consist of two (rearrangement/cyclization) or three steps (sulfide formation/rearrangement/cyclization) proceeding often rapidly without isolation of intermediates. The rearrangement depends on the nature of sulfides, steric hindrance, reaction conditions (basic, but also weakly and strongly acidic, and even neutral and thermal). Some reaction conditions and catalysts favor direct cyclization. This review arranges the knowledge of the Smiles rearrangement of phenyl azinyl and diazinyl sulfides but also systematizes the syntheses of monoaza-, diaza-, triaza-, tetraazaphenothiazines and their benzo- and dibenzo derivatives. The review shows that some formed azaphenothiazines were wrongly identified and not all wrong structures have been corrected. Some syntheses cannot be defined as proceeding with the rearrangement or not when both the rearranged and direct products are the same. The structure analysis of resulted azaphenothiazines is crucial (the most reliable: X-ray analysis or two-dimensional NMR). The authors hope that this review will prompt researchers to revisit some syntheses of azaphenothiazines. (C) 2020 Elsevier B.V. All rights reserved.

2-Acetylbenzimidazole: a Valuable Synthon for the Synthesis of Biologically Active Molecules

Benzimidazole is an important moiety from a medicinal chemistry perspective due to its various biological activities such as antimicrobial, anti-cancer, anti-diabetic, anti-Alzheimers, and anti-inflammatory, etc. 2-acetylbenzimidazole is exploited to obtain various heterocyclic compounds of pharmacological interest. 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.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 154445-78-0.
