Abstract

New proline diamide organocatalysts with Pro-Phe peptide bonds were synthesized and their catalytic activities in asymmetric direct aldol reactions of aliphatic ketones with aromatic aldehydes were investigated. Catalyst 6a showed good enantioselectivity at 0 degrees C in the presence of p-nitrobenzoic acid as cocatalyst in water.
