✦ Synopsis


The allylation of acylsilanes with tetraallyltin in the presence of catalytic amounts of Sc(OTI) 3 proceeded smoothly to afford the silylated homoallylic alcohols in good yields. Subsequent protiodesilylation gave the formal adducts of the corresponding aldehydes. The homochiral acylsilane II gave a reversal of as) mmetric induction in the Sc(OTf) 3 catalyzed allylation and in the Sakurai reaction.
