diastereoselective addition of gamma-substituted allylic nucleophiles to ketones has been accomplished to give tertiaryhomoallylicalcohols. The reaction of tributylcinnamyltin 1a with simple ketones 2 in the presence of stannous chloride (SnCl(2)) gave the tertiaryhomoallylicalcohols 3, which include the anti form (based on Ph and OH), with high diastereoselectivity. In the reaction course, transmetalation
