Procedure

1.0 g. of the 7-allyl-enone 72, 5 ml. EtOAc and 50 mg. triphenylphosphine rhodium chloride (Wilkinson's catalyst) were allowed to stir two hours (under H2 atmosphere). The reaction products were filtered through 25 ml. silica gel, and evaporated to dryness to yield fairly pure title product, 76, as confirmed by proton NMR.
