The Claisen rearrangement of 7-(3-phenyl-2-propenyloxy)-3-phenyl-(4H)-1-benzopyran-4-one (2a) gave 7-hydroxy-8-(1-phenyl-2-propenyl)-3-phenyl-(4H)-1-benzopyran-4-one (3a) and 2,3-dihydro-2,6-diphenyl-3-methyl-(7H)furo-benzopyran-7-one (7a). 2-Methy

7-Cinnamyloxy derivatives (2a, 2b, 2c) of noreugenin, 2-methylisoflavone and chrysin undergo Claisen rearrangement in refluxing quinoline to yield 8-(1-phenylprop-1-enyl) derivatives (3d, 3g, 3i respectively) and 4'-methyl-5'-phenylfuro[2',3':7,8] derivatives (4l, 4m, 4o respectively) as abnormal products. These have features similar to those of natural neoflavonoids.
