Through a suspension of 800 mg (4.2 mmol) of olefin 149 and 100 mg of 10% palladium on carbon was bubbled a steady stream of hydrogen gas for a period of 10 min. The reaction mixture was then filtered through celite and concentrated to give 805 mg of the acetal 150 as a colorless oil. 1H NMR consistent with structure.
