    摘要: Preparation of a methyl ketone intermediate useful in the synthesis of (-)-dodecahydro-3a,6,6, 9a-tetramethyl-naphtho(2,1-b) furan by subjecting (-)-sclareol to ozonolysis in the presence of iodine or iodine-containing compound. The intermediate can be converted to (-)-dodecahydro-3a,6,6,9a-tetramethyl-naphtho(2,1-b) furan by Baeyer-Villiger oxidation followed by reduction of the resulting product in the presence of a Lewis acid.
