  A short and facile synthetic route to hydroxylated flavones. New syntheses of apigenin, tricin, and luteolin

  摘要：

  Reaction of the lithium polyanions generated from omicron-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 0.5% H2SO4 at 95-100-degrees-C afforded hydroxylated flavones 5-18 in high yields (76-92%).
