A novel and efficient route for the syntheses of hydroxylated 2,3-diarylxanthones

A novel, efficient and general route for the synthesis of hy-droxylated 2,3-diarylxanthones is described. 3-Bromo-2-styrylchromones, the key intermediate of this synthesis, is obtained by a Baker-Venkataraman rearrangement of appropriate 2’-cinnamoyloxyacetophenones, followed by a one-pot reaction w...
