Abstract
On irradiation in benzene, 5,7-dimethyl-4′-methoxyflavanone gave a bis-flavanone V, while in 2-propanol it was largely recovered. Irradiation of 4′-methoxyflavanone in benzene and 2-propanol yielded the corresponding chalcone and pinacols, respectively. 5,7,4′-Trimethoxyflavanone was relatively inert to photolysis in benzene, but gave a complex mixture of products in 2-propanol.Keywords
