Abstract
2-Methyl-4H-pyran-4-ones formed metalated products in the presence of sodium amide in liquid ammonia, and the metalated product reacted with alkyl and aralkyl halides or carbonyl compounds to give alkylated or condensed products. Self condensation reactions of 2-methyl-4H-pyran-4-ones also occurred in liquid ammonia to give flavone and the γ-pyrone dimer.
