N-Tosyliminium species, prepared in situ from carbonyl compounds and TsNH2 with SnCl2 and N-chlorosuccinimide, undergo nucleophilic addition of allylic silanes (imine allylation) to produce the corresponding homoallylic amines; the imine allylation by but-2-enyltrimethylsilane with aldehydes and TsNH2 leads to regio- and diastereo-selection to produce anti 1-substituted 2-methylbut-3-enylamines.
