The asymmetric alkylation with diethylzinc of five heterocyclic aldehydes and benzaldehyde (for comparison) has been studied in the presence of two optically active amino alcohols: (S)-2-amino-1-butanol (AB) and (1S,2R)-N,Ndibutylnorephedrine (DBNE).

High levels of enantioselectivity have been achieved in the diethylzinc addition to both aromatic and aliphatic aldehydes, employing readily available N-substituted-azetidinyl(diphenylmethyl)methanols as chiral catalysts.
