摘要
Chiral phosphoramides prepared from (S)-proline were used to catalyze the allylation and crotylation of aromatic aldehydes with allylic trichlorosilanes in good enantioselective yields. Phosphoramides 4d and 4m gave chiral homoallylic alcohols and their enantiomers, respectively, with similar levels of enantioselectivity. (C) 1997 Elsevier Science Ltd.
