Eleven chiral trivalent or quatrivalent phosphorus reagents were synthesized starting from L-proline, D-camphor, (+)- or (−)-1,1′-binaphthalene-2,2′-diol, (−)-α-phenylethylamine, etc. and their application as catalysts in asymmetric borane reduction of N-phenyl imine of acetophenone was preliminarily investigated. N-Phenyl α-phenylethylamine was obtained in good yield with low to moderate enantioselectivity
以 L-脯氨酸、D-樟脑、(+)- 或 (-)-1,1'-联萘-2,2'-二醇、(-)-α-苯乙胺为原料合成了 11 种手性三价或四价磷试剂,初步研究了它们作为催化剂在苯乙酮N-苯基亚胺不对称硼烷还原反应中的应用。N-苯基α-苯乙胺以良好的收率获得,具有低至中等的对映选择性。© 2003 Wiley Periodicals, Inc. 杂原子化学 14:546–550, 2003; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.10190
