The first organocatalytic enantio­selective transfer hydrogenation of nitroolefins using a Jacobsen-type thiourea catalyst is reported. A broad substrate scope of this reaction is shown. With 5-10 mol% of catalyst good yields (82% to >99%) and high enantioselectivities (er: up to 98:2) are obtained. Aliphatic, aromatic, and sterically hindered substituents R1 in β-position are well tolerated.
