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

The properties of 4,5-dihydro-2-methylbenzothiazol-7(6H)-one have been investigated and this readily accessible ketone has been used for preparing thiazoloacridines, thiazolocarbazoles, and benzo-thiazolocarbazoles.
The reaction between aliphatic amines and bromohydrins derived from 1‐tetralone derivatives or 7‐oxo‐tetrahydrobenzothiazole is reported. In both cases trans‐aminoalcohols with the amino group in the benzylic position are obtained. These aminoalcohols then give their corresponding azirine derivatives.
