Abstract Thiazole derivatives represent an important class of azole heterocycles with a broad spectrum of biological activity and, therefore, the synthesis of these compounds is of remarkable concern. We present here practical and reliable protocol for synthesis of some 5-acylthiazoles and demonstrate their utility in the preparation of several new series of thiazole-containing building blocks through transformation of 5-acyl function. Specifically, thiazole-based alcohols, oximes, primary, and secondary amines were successively synthesized in good to excellent yields. The chemical structures of obtained compounds were confirmed by 1H and 13C NMR-spectroscopy, elemental analysis, and mass-spectrometry. Graphical Abstract
