Abstract
The asymmetric direct aldol reactions of a wide scope of aldehydes with unmodified ketones in the presence of 20 mol%(S,S,S)-pyrrolidine-2carboxylic acid (2ʹ-hydroxyl-1ʹ,2ʹ-diphenyl-ethyl)-amine (1) were performed in ionic liquids; aldol products with 91 to >99% ees for aromatic aldehydes and 99% ees for alphatic aldehydes were offered by the present procedure.
