Abstract

Regio- and diastereoselective reduction of chiraltrifluoromethyl α,β-unsaturated N-tert-butanesulfinyl ketoimines 1 was achieved by choosing appropriate reducing agent and either diastereomer of the corresponding trifluoromethylated allylic amines was obtained with good yield and excellent diastereoselectivity (up to >99 : 1 dr).
