Boron Trifluoride Etherate Catalysed Rearrangement of Dihydropyranochalcone Epoxides: Synthesis of Dihydropyranoisoflavones and Their Dehydro-analogs

6-Acetyl-7-hydroxy-2,2-dimethylchroman (I) and 6-acetyl-7-methoxy-2,2-dimethylchroman (II) on condensation with the arylaldehydes (IIIa-d) give the dihydropyranochalcones (IVa-f).The O-benzylated chalcones (Va-f) are oxidised with alkaline hydrogen peroxi
