摘要

Reaction of 4-oxo-4H-[1]-benzopyran-3-carboxaldehydes with 3-methyl-1-phenylpyrazolin-5(4H)-onein dioxane in the presence of triethyl amine affords 3-methyl-4-[(chromon-3-yl)methylene]-1-phenylpyrazolin-5(4H)-ones 3a-k. condensation of 3 with thiourea in alcoholic KOH under reflux yields 2-thio-5-hydroxy-5H-[1]-benzopyrano[4,3-d]pyrimidines 6a-h.
