Background: While proline can catalyze the asymmetric direct aldol reactions, its catalytic activity and catalyst turnover are both low. To improve the catalytic efficiency, many prolinebased organocatalysts have been developed. In this regard, proli

Enantioenriched secondary α-hydroxycarboxylates have been synthesized in good yields and enantioselectivities by using the cross-aldol reaction of ketones and ethyl glyoxylate with a -proline-derived dipeptide as the catalyst.
