Abstract
Boron trifluoride-etherate reacts with 2'-benzyloxychalkone epoxides to give mainly dihydroflavonols if ring B is unsubstituted, but isoflavones are formed by rearrangement if methoxy groups are present in positions 4 or 3 and 4. These factors limit the applicability of isoflavone synthesis using chalkone epoxides.
