title: Allylation and highly diastereoselective syn or anti crotylation of N-toluenesulfonylimines using potassium allyl- and crotyltrifluoroborates.
abstract: Air and moisture stable potassium allyl- and crotyltrifluoroborates undergo addition to N-sulfonyl and N-sulfinyl aldimines in the presence of Lewis acids, to provide the corresponding homoallylic amines in high yields and excellent diastereoselectivity.
