| Abstract: | Treatment of 3-(2-bromoacetyl)coumarins with potassium thiocyanate provides 3-(2-thio-cyanatoacetyl)coumarins which on treatment with methanolic.HCI gives 3-(2-hydroxy-4-thiazolyl)-2H-l-benzopyran-2-ones (2) but not oxathiole derivative (4a) or 3-(2-chloro-4-thiazo!yl)coumarins (4b). 2 undergoes smooth condensation with alkyl, aralkyl halides to give corresponding ethers. The structure of newly synthesized compounds were established on the basis of spectral data (IR, PMR and MS) |
