Abstract
Condensation of cyanomethyl derivatives of benzimidazole and benzothiazole with resorcinol gave the corresponding 2,4-dihydroxy-α-hetarylacetophenones. The latter were converted to 3-hetarylchromones with methyl, trifluoromethyl, and ethoxycarbonyl groups in the 2 position or to chromones without substituents in this position.
