Abstract

Conformationally constrained, optically active 1,4-aminoalcohols have been used Lis chiral ligands in the addition of diethylzinc to aromatic aldehydes. The enantioselectivity was strongly influenced by the N-alkyl group: the best results were achieved with N-ethyl- and N-benzyl-aminoalcohols (ees up to 95% and 81%, respectively). One example of addition to an aliphatic aldehyde is also reported (best ee 61%).
