Carbohydrate as a kind of important chiral scaffold is widely recognized for its obvious advantages cheap and
readily available. A new type of prolinamide organocatalysts, derived from carbohydrate, was synthesized in
high yield, and the novel organocatalysts were applied to the direct asymmetric aldol reactions of cyclohexanone
and various aromatic aldehydes. The corresponding aldol products were obtained in high yields (up to 99%) with
excellent diastereoselectivities (up to N 98:2 dr) and enantioselectivities (up to 97% ee) under mild reaction
conditions
