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.

This article describes a facile synthesis of 2-substituted-5-(ketoaryl)thiazoles, which are important intermediates for the synthesis of biologically active compounds. A variety of 2-substituted thiazole anions were added to aryl nitriles to provide the desired ketones after aqueous hydrolysis.
