Abstract
Novel tetracyclic lactone (5a), 9-ethoxycarbonyl-10(10aH)-oxo-5,6,- 7,8,8a, 9-hexahydro-9, 10a-anthracenecarbolactone, was obtained in 34.8% yield by o xidative cyclization of diethyl trans-2-benzoylcyclohexylmalonate (4a) with manganese(III) acetate dihydrate in the presence of sodium acetate in acet ic acid.
