摘要：

3-Arylallyltin reagents including cinnamyltin stereoselectively gave anti-adducts in the ZnCl2-mediated reaction toward aldehydes in a donating solvent via the 6-membered cyclic transition state. In contrast, the BF3-mediated reaction gave syn-adducts via the acyclic transition state. The present result corrects the previously reported stereochemical determination of the BF3-mediated product.
