A Study of the Claisen Rearrangement of 7-(3-Phenyl-2-propenyloxy)-3-phenyl-(4H)-1-benzopyran-4-one Derivatives

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

Claisen Rearrangement of Some 7-Cinnamyloxychromones

The 7-cinnamyloxychromones (2a, 2b and 7) undergo Claisen rearrangement in refluxing N,N-dimethylaniline to give 8-(1-phenyl-2-propenyl) derivatives (4a, 4d and 8 respectively) as normal products in good yields.These have features similar to those of natu
