실험 절차

A mixture of 1.104 g. (4.084 mmoles) of (3R,7R)-E-Ethyl 8-tert. butoxy-3,7-dimethyl-4-octenoate, a small amount of Raney nickel, and 30 ml. of ethyl acetate was stirred in an atmosphere of hydrogen, at room temperture, for 2 hours during which time approximately one equivalent of hydrogen was taken up. The catalyst was filtered off and washed with ethyl acetate. Concentration of the combined filtrate and washes in vacuo followed by evaporative distillation afforded 1.045 g. (95%) of saturated ester (3S,7R)-Ethyl 8-tert. butoxy-3,7-dimethyloloctanoate as a colorless oil, b.p. 80°-83° C. (bath temperature) (0.15 mm Hg.).
