Ionic liquid-supported (1S,2S)- and (1R,2R)-1,2-bis[(S)-prolinamido]-1,2-diphenylethanes act as organocatalysts in asymmetric aldol reactions of acetone with α-keto esters or trifluoroacetophenone providing high yields and from moderate to high enantio-se

A new efficient and highly recyclable organocatalyst has been developed for asymmetric cross-aldol reactions under neat conditions in ketone-ketone, ketone-aldehyde, and aldehyde-aldehyde systems. The catalyst features two prolinamide fragments and a Csu

In prime condition: The hydrolysis of a chiral diimine precursor can be carried out by a Bronsted acid to form an in situ primary amine-imine intermediate as a bifunctional primary aminocatalyst, which promoted direct asymmetric aldol reactions between α-
