Several C2 symmetric molecules were tested as organocatalysts for the direct catalytic asymmetric aldol reaction of cyclohexanone with 4-nitrobenzaldehyde. (2S,5S)-Pyrrolidine-2,5-dicarboxylic acid afforded the best results for this transformation. The reaction of a series of aromatic aldehydes with cyclohexanone was carried out in DMSO using a catalyst loading of 30 mol% at 10 ℃, and the aldol adducts were obtained in 87%~99% ee.

Key words: direct aldol reaction, organocatalyst, cyclohexanone, enantioselective catalysis
