| Abstract: | Condensation of 5-pyrimidine carboxylic acid 1,2,3,4-tetrahydro-6-methyl-4-phenyl-2-thioxoethyl ester II with various 3-(2-bromoacetyl)coumarins I, followed by the PPA cyclization of the intermediate ketones III, yielded 3-(2-oxo-2H-chromen-3-yl)-7-methyl-5-phenyl-5H-thiazolo[3,2-a]pyrimidine-6-carboxylicacid ethyl esters IV. The structures of newly synthesized compounds have been confirmed from analytical and spectral data. |
