| Abstract: | The treatment of 3-[3-(dimethylamino)-1-oxo-2-propenyl]chromen-2-ones with 3-amino-4-cyanopyrazole gives 7-(2-oxo-2H-chromen-3-yl)pyrazolo[1,5-a]pyrimidine-3-carbonitriles. The reaction of 3-(2bromoacetyl)coumarins with 2-amino-4-(methoxycarbonylmethyl)thiazole and 2-amino-4-methylthiazole gives methyl 2-(6-(2-oxo-2H-chromen-3-yl)imidazo[2,1-b]thiazol-3-yl)acetate and 3-(2-methylimidazo[2,1-b]thiazol-6-yl)-2H-chromen-2-ones, respectively. |
