摘要
Chiral di- or triamines, (S)-2-(N,N-disubstituted aminomethyl)indoline 1a-d, derived from (S)-indoline-2-carboxylic acid were efficient chiral catalysts for the enantioselective addition of dialkylzincs to aldehydes. The best results were obtained by employing 15 mol% of (S)-2-(4-methylpiperazin-1-ylmethyl)indoline Ic, and chiral secondary alcohols were obtained in up to 97% ee. (C) 1998 Elsevier Science Ltd.
