A Short and Facile Synthetic Route to Hydroxylated Flavones. New Syntheses of Apigenin, Tricin, and Luteolin

Reaction of lithium polyanions generated from o-hydroxyacetophenones 3a-f with O-silyloxylated benzoates 2a-d gave 1-aryl-3-(2-hydroxyphenyl)-1,3-propanediones 4a-n, which on treatment with acetic acid containing 0.5percent H2SO4 at 95 - 100 deg C afforded hydroxylated flavones 5-18 in high yields (76 - 92percent).
