Baker‐Venkataraman Rearrangement

Abstract

The rearrangement of o ‐acyloxyketones into β‐diketones under basic conditions is generally referred to as the Baker–Venkataraman rearrangement or Baker–Venkataraman transformation. This intramolecular acyl transfer reaction has become a major reaction in flavone chemistry and the migration of acyl group has been confined to aromatic or heteroaromatic acyl group. The resulting molecules from this reaction have been applied to the synthesis of chromones and flavones.
