Abstract

3-Hetaryl-7-methoxychromones were obtained by reaction of α-(5-ethoxycarbonyl-2-furyl)-, α-(2-benzofuryl)-, and α-(2-methoxy-carbonyl-5-benzofuryl)-2-hydroxy-4-methoxyacetophenones with methyl formate or ethyl orthoformate, and 3-hetaryl-4-hydroxy-7-methoxy-coumarins were obtained by reaction of the same compounds with diethyl carbonate. Methods for the synthesis of 3-hetaryl-7-hydroxy-chromones from α-furyl- and α-benzofuryl-substituted, 2,4-dihydroxyacetophenones were investigated.
