Baker-venkataraman rearrangement under microwave irradiation: A new strategy for the synthesis of 3-aroyl-5-hydroxyflavones

Pinto, Diana C. G. A.,Silva, Artur M. S.,Cavaleiro, José A. S.

, p. 1897 - 1900 (2008/03/13)

Microwave irradiation selectively induces the Baker-Venkataraman rearrangement of 2′,6′-diaroyloxyacetophenones to give 3-aroyl-5-hydroxyflavones, in a very short reaction time. Under classical heating conditions these reactions afforded 5-hydroxyflavones
