Synthesis of 2,3-disubstituted-6-chromones of potential medicinal interest

The title compounds (12-19) have been synthesized by the condensation of 2,3-disubstituted-6-chromones (8-11) with hydrazine hydrate in the presence of formic or acetic acid.Their structures have been elucidated on the basis o

Synthesis of 6-Cinnamoylchromones

Synthesis of 6-cinnamoyl-2,3-dimethylchromones (4), 6-cinnamoyl-3-methyl-2-phenylchromones (5) and 6-cinnamoyl-3-methylchromones (6) from 5-cinnamoyl-2-hydroxypropiophenone (3) has been described.The structures of the compounds have been brought out on th

Synthesis of 6-Acetyl-3-alkyl-2-phenyl-chromen-4-ones by Phasetransfer Catalysed Baker-Venkataraman Reaction

Three of the five partial steps of the Baker-Venkataramansynthesis of flavones (scheme 1) can be flavoured by PTC conditions.In the intermolecular O-acylations of the 4-hydroxyacetophenone 1 (A) and the 5-acetyl-2-hydroxy-acylophenones 3 (C), respectively, the nucleophilicity of the phenolat anions is increased by the PT catalysator.The steric and electronic effects of the substituents in the 5-acetyl-2-benzoyloxy-acylophenones 4 cause the formation of the 6-acetyl-flavones 6 in the phasetransfer catalysed Baker-Venkataraman rearrangement (D) in one step and in good yields.The over-all yields of the 1 -> 6 reactions are not higher than 30percent because of the limiting step (B).This Fries rearrangement of 4-acyloxy-acetophenones 2 affords only 32-62percent of 3 under drastically enhanced conditions.
