Abstract

Sodium hydroxide controlled intermolecular double aldol condensation of o-hydroxyacetophenones with 2 equivalents of aryl­aldehydes provides 2-aryl-3-(arylmethyl)chromones (a chimera of flavone and homoisoflavanone) in MeOH at 50 °C under mild conditions. The uses of various bases and solvents are investigated for one-pot facile and efficient transformation. A plausible mechanism is proposed.
