Abstract

A greener and direct approach to the efficient synthesis of fused heterocyclic ring system benzo[4,5]imidazo[2,1-b]thiazoles via C–N and C–S bond formation in catalyst-free conditions has been reported using 2,2,2-trifluoroethanol (TFE) as a reaction medium at room temperature. The salient features of this approach include an elementary and clean reaction protocol to afford the desired product in higher yields in less reaction time with sufficient purity. This prominent moiety is frequently found in many natural bioactive occurring compounds and shows potential in synthesizing diverse biologically active compounds due to their therapeutic values. The synthesis of benzo[4,5]imidazo[2,1-b]thiazoles was confirmed by spectral analysis and also by DFT studies.

期刊介绍: The Journal of Sulfur Chemistry is an international journal for the dissemination of scientific results in the rapidly expanding realm of sulfur chemistry. The journal publishes high quality reviews, full papers and communications in the following areas: organic and inorganic chemistry, industrial chemistry, materials and polymer chemistry, biological chemistry and interdisciplinary studies directly related to sulfur science. Papers outlining theoretical, physical, mechanistic or synthetic studies pertaining to sulfur chemistry are welcome. Hence the target audience is made up of academic and industrial chemists with peripheral or focused interests in sulfur chemistry. Manuscripts that truly define the aims of the journal include, but are not limited to, those that offer: a) innovative use of sulfur reagents; b) new synthetic approaches to sulfur-containing biomolecules, materials or organic and organometallic compounds; c) theoretical and physical studies that facilitate the understanding of sulfur structure, bonding or reactivity; d) catalytic, selective, synthetically useful or noteworthy transformations of sulfur containing molecules; e) industrial applications of sulfur chemistry; f) unique sulfur atom or molecule involvement in interfacial phenomena; g) descriptions of solid phase or combinatorial methods involving sulfur containing substrates. Submissions pertaining to related atoms such as selenium and tellurium are also welcome. Articles offering routine heterocycle formation through established reactions of sulfur containing substrates are outside the scope of the journal.
