Over 20 new and easily prepared diamines were screened for the asymmetric Morita-Baylis-Hillman reaction. Chiral non-racemic 3-(N,N-dimethylamino)-1-methylpyrrolidine was found to promote efficiently the reaction of methyl vinyl ketone and substituted benzaldehydes. Enantiomeric excesses up to 73% were reached with electron-deficient benzaldehyde derivatives. After a simple deprotonation, one of these diamines was transformed into a chiral mixed aggregate for the enantioselective synthesis of (R)-1-o-tolylethanol with 76% ee. (C) 2010 Elsevier Ltd.
