The regio- and stereo-selective epoxidation of methyl 3,4-dihydrobenzoate derivatives has been investigated. Perbenzimidic acid leads only to epoxides formed at the Δ1,2 bond. More electrophilic reagents such as MCPBA also give products of this type, as well as epoxides formed through attack at the Δ5,6 bond. Reactions of the 3,4-dihydrobenzoates with thiophenate anion have been undertaken as a means
