5750 J. Org. Chem. 1991,56,5750-5752 has been suggested to account for the dependence of product configuration on Lewis acid stoichiometry in the reactions of aldehydes with allyl~netals.~~ Because WCl is not capable of forming a pentacoordinated 21 complex, it shows no change in selectivity as a function of equiva- lents of Lewis acid. ................
