enantioselective Henry addition of methyl 4-nitrobutyrate to aldehydes using a Cu(II)−amino pyridine complex as catalyst is described. The products resulting from this reaction constitute a new, highly versatile family of chiralbuildingblocks as a result of the presence of three different functional groups on the molecule. These products have been transformed into nonracemic chiral γ-lactams, 5-hydroxy-5-substituted
