Several new chiral allylstannanes were prepared and reacted with aldehydes. Excellent diastereofacial selectivity was observed for the reactions of allylstannane 1 with aldehydes in the presence of BF3·Et2O. This is in contrast to the results from other allylstannanes which do not bear a β-methyl group. These observations were rationalized based on a combination of steric and electronic effects.
