Cyclohexanones 1 were allowed to react with allyltrimethylsilane and three allyltributylstannanes in the presence of titanium tetrachloride.Products 2 and 3 were formed in ratios ranging from 7:1 to 26:1 (2:3).Ratios resulting from the use of other Lewis acids support 4 as an intermediate which accounts for the observed stereoselectivity.
