Practical synthesis of a highly functionalized thiazole ketone
摘要:
Compound 1 is a uniquely substituted ketone prepared via addition of a thiazole anion to an aromatic nitrile in good overall yield. An exploration into the generality of the addition of thiazole anions to nitriles allowed us to make a variety of thiazole ketones in good to excellent yields. The non-odorous thiolate-mediated demethylation reaction used in the synthesis of 1 is also presented. (C) 2003 Elsevier Ltd. All rights reserved.

A practical and highly effective one-pot synthesis of versatile heteroaryl ketones directly from carboxylic acids and heteroaryl halides under mild conditions is reported. This method does not require derivatization of carboxylic acids (preparation of acid chlorides, Weinreb amides, etc.) or the use of any additives/catalysts. A wide substrate scope of carboxylic acids with high functional group tolerance

An electrochemical method for the synthesis of 2-aminothiazoles via aryl ring construction using enaminones and thioureas is reported. The cascade enamine C–H thiolation and C–N amination constitutes a major transformation for the thiazole ring formation. Moreover, a simple modification of electrochemical conditions enables the tunable dearomatization of the thiazole ring via vicinal dialkoxylation
