Isomerisation of 3-Benzylidene-4-chromanones in Presence of Alkali

3-Benzylidene-4-chromanones (Ia-d) having 7-methoxy, 7-benzyloxy- or 5,7-dimethoxy groupings in ring-A undergo alkali isomerisation to yield both the corresponding 3-benzyl-4-chromones (IIa-d) and 3-methylflavones (IIIa-d).Hence both the types of isomeris
