An approach to asymmetric catalysis based on chiral molecular recognition by the combination of chiral Lewis acids and chiral organocatalysis for the formation of optically active quarternary centers in the aza-Henry reaction is presented; this procedure leads to products with up to 98% ee and a diastereomeric ratio of 14 : 1 in excellent yields with catalyst loadings of 5 mol%.
