Baker-Venkataraman (BV) rearrangement is the method of choice for the synthesis of flavones. The major
limitation of BV is that it requires extensive protections and deprotections of hydroxyl groups which make the process
lengthy and cumbersome. In the present study, a three step efficient method has been developed using simple protecting
groups and easily available starting materials. New syntheses for acacetin, chrysoeriol, diosmetin, tricin and other
hydroxylated flavones are described.
Keywords: Baker-Venkataraman transformation, partial methyl ethers, polyhydroxyflavones.
