摘要

Manganese (III) acetate in acetic acid promotes efficient radical-mediated oxidative cyclisation of ε-aryl-β-dicarbonyl and Z-γ, δ-unsaturated δ-aryl-β-dicarbonyl compounds carrying electron-releasing groups in the aromatic ring, forming 6, 7, 8, 9-tetrahydro-5H- benzocyclohepten-6-ones and naphthalen-2 (1H)-ones, respectively. The process is accompanied by secondary acetoxylation at the activated benzylic position of the initial ...
