Abstract

A number of thiazolopyrimidines (II–VII) were prepared through interaction of 6-methyl-4(4′-chlorophenyl)-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid ethyl ester (Ia) with many reagents. The antifungal activity of all prepared compounds have been determined using Dithane M-45 as a standard fungicide. Some compounds showed a high fungicidal activity equivalent to that of the standard towards Aspergillus niger and Aspergillus ochraceus. Also some biologically active compounds were subjected to gamma irradiation and the structures are stable.
