A concise synthesis of 3-aroylflavones via Lewis base 9-azajulolidine- catalyzed tandem acyl transfer-cyclization

Lewis base-catalyzed tandem acyl transfer-cyclization of acylated o-alkynoylphenols leading to 3-aroylflavones was developed. 9-Azajulolidine smoothly promoted the reaction of the aroyl derivatives at ambient temperature, and the structure-diversed synthesis of 3-aroylflavones with distinct substituents was achieved in moderate to excellent yields.

Synthesis and properties of 3-acyl-γ-pyrones, a novel class of flavones and chromones

Using modified Baker-Venkataraman reaction a novel class of 3-acyl flavones and chromones have been synthesised. Reaction mechanism for their formation have been elucidated. The properties of 3-acyl flavonoids indicate them to be precursors for the synthesis of flavones.

Novel One-pot Photochamical Synthesis of 3-C-Aroyl-2-aryl-4H-1-benzopyran-4-ones

Methylene blue sensitized photooxygenation of 3-arylidene-2-aryl-2,3-dihydro-4H-1-benzopyran-4-ones (1a-d) has provided 3-C-aroyl-2-aryl-4H-1-benzopyran-4-ones (2a-d) in moderate to good yield.A plausible mechanism for the reaction involved has been suggested.
