A series of novel chiral imines was synthesized from corresponding aldehydes and
1-(2-aminoalkyl)aziridines with good chemical yields. Such imines were tested as catalysts in the
direct asymmetric aldol reaction between aromatic aldehydes and acetone/cyclohexanone in the
presence of catalytic amounts of water and an acidic additive. The corresponding aldol products were
formed in excellent yields and with very high enantioselectivities (98% and 99% ee, respectively).
