Abstract The condensation of cyanomethyl derivatives of furan and benzofuran with di- and trihydric phenols has given the corresponding 2,4-dihydroxy- and 2,4,6-trihydroxy-α-heterylacetophenones. The latter have been converted by reaction with acid anhydride, ethoxalyl chloride, and trifluoroacetic anhydride into 3-heterylchromones with methyl, trifluoromethyl, and ethoxycarbonyl groups in position 2.
