Abstract

Treatment of B-ring substituted 5, 7-dihydroxy flavones with alkyl halides in the presence of potassium carbonate gave unexpected 3-alkylated flavonoids. Related experiments were carried out to explain the formation of 3-alkylated flavonoids and a ring opening followed by alkylation and ring closure mechanism was proposed.
