Abstract In a one-pot procedure, CuBr2 has been used as a efficient desulfurizing agent in the synthesis of 2-aminothiazoles by the condensation of in situ-generated 1-substituted thioureas from their dithiocarbamic acidsalts, with in situ-generated α-bromoketones from ketones. All reactions were carried out under optimized reaction conditions and gave the target products in 61–95% yield.
Several straightforward and practical processes have been established for the construction of 2-aminothiazoles, 1,3-thiazoles and 1,3-selenazoles from aryliodoazides. These strategies successfully proceed with a wide spectrum of substituted thioamides and its derivatives producing the resulting five-membered heterocycles obtained in satisfactory yields. The unique features of these protocols are operational

Regioselective condensation of α‐tosyloxyacetophenones 1 and N‐substituted thioureas 2 in acidicmedium to give regioisomers 2‐aminothiazoles I and 2‐imino‐2,3‐dihydrothiazoles II is largely influenced by the substituents present on 1 and 2. A mechanism, supported by DFT calculations has been proposed to explain the observed regioselectively.

The identification of a proper lead compound for fructose 1,6-bisphosphatase (FBPase) is a critical step in the process of developing novel therapeutics against type-2 diabetes. Herein, we have successfully generated a library of allosteric inhibitors against FBPase as potential anti-diabetic drugs, of which, the lead compound 1b was identified through utilizing a virtual high-throughput screening (vHTS) system, which we have developed. The thiazole-based core structure was synthesized via the condensation of alpha-bromoketones with thioureas and substituents on the two aryl rings were varied. 4c was found to inhibit pig kidney FBPase approximately fivefold better than 1b. In addition, we have also identified 10b, a tight binding fragment, which can be use for fragment-based drug design purposes. (C) 2009 Elsevier Ltd. All rights reserved.
