The Reformatsky reaction of bromodifluoromethyl ketones and imines took place readily in the presence of Zn/CuCl at room temperature to afford β-amino α,α-difluoro ketones in good yields. Using (S)-tert-butanesulfinyl as a chiral auxiliary, the asymmetric Reformatsky reaction was also achieved and found to proceed with excellent diastereoselectivities. A plausible model is proposed to account for the

A highly practical and efficient asymmetric synthesis of chiral homoallylic amines by In-mediated allylation of chiral N-tert-butanesulfinyl imines in aqueousmedia at room temperature was developed. With 2-formylbenzoate imine substrates, the method allows the highly enantioselective achievement of a variety of pharmacologically important 3-allyl isoindolinone compounds.
