Abstract

A highly enantioselective Michael addition of aromatic ketones to α,β,γ,δ-unsaturated nitro compounds is described. In the presence of a chiral primary amine-thiourea based on dehydroabietic amine, γ-nitro ketones were obtained in excellent enantioselectivities (up to 95% ee) with up to 95% yield. In addition, this methodology has been successfully applied in the asymmetric synthesis of chiral 3-(aminomethyl)-5-phenylpentanoic acid.
