Solventfree asymmetric aldol reaction organoalyzed by

An efficient, solventfree ballmilling protocol for the asymmetric aldol reaction between cyclohexanone and cyclopentanone with various aromatic aldehydes using a novel series of (S)prolinecontaining dipeptides and thiodipeptides 1a–f as organoalysts is reported.In general, (S)prolinecontaining thiodipeptides proved to be better organoalysts relative to their analogous amides.
