Two sets of results give information about the mechanism of carbonyl activation by (S)-proline during asymmetric syntheses; (i) X-ray structures of two ketols produced by the proline-induced cyclization of triketones; (ii) (S)-proline-catalyzed asymmetric dehydratation of (+/-)-β ketols leading to optically active enones.
