A convenient method was developed for the synthesis of hydroxymethyl and carboxaldehyde derivatives of 3,5-diphenyl-4H-pyran-4-one from their corresponding bromomethyl derivatives by treatment with silver acetate followed by hydrolysis and oxidation. Compounds, 3,5-diphenyl-2-hydroxymethyl-6-methyl-4H-pyran-4-one (4a), 2,6-bishydroxymethyl-3,5-diphenyl-4H-pyran-4-one (7a), 3,5-diphenyl-6-methyl-4-oxo-4H-pyran-2-carboxaldehyde (3a), and 3,5-diphenyl-4oxo-4H-pyran-2,6-dicarboxaldehyde (6a) were obtained.
