Abstract
[reaction: see text] An efficient method for the highly diastereoselective synthesis of chiral homoallylic amines by Zn-mediated allylation of chiral N-tert-butanesulfinyl imines at room temperature was developed. By simply tuning the reaction conditions, the method allows the achievement of a highly remarkable opposite stereocontrol, affording the desired stereochemical outcome in good yield and with excellent diastereoselectivity (up to 98% dr). With N-sulfinyl ketimines, the corresponding quaternary carbon-containing chiral homoallylic amines could also be produced.
