Abstract: Chiral amino alcohol in the field of asymmetric synthesis is a kind of important chiral source, at the same time,chiral amino alcohol has extensively applicates in drug synthesis and separation raceme with broad areas . In this paper，the inspection on the based of the relevent summarizes the asymmetric catalytic reduction of new progress. In order to find the catalytic performance,based on more catalysis center ligand in asymmetric caltalytic reduction of synergies，can achieve available chiral seconddary alcohols higher e.e. value. We were respectively using (1R, 2S )-(-) and (1S, 2R )-(+)- 2 - amino -1,2 – diphenyl ethanol as chiral sources with 1，3-benzyl bromide reponse by optimizing the reaction conditions in acetonitrile solution，in the 60-65℃，KI as a catalyst，K2CO3as a hydrogen absorption reagent first synthesized the catalysis center with the ligand： N-(1'R, 2'S) - (1 ', 2'- diphenyl -2 '- hydroxy) and N-(1'S, 2'R) - (1', 2'-diphenyl -2 '- hydroxy) ethyl -1’,3’- benzyl amine,by silica gel column chromatograp get the colorless crystal, yields are higher . Product by the IR、MS and 1HNMR，ect. Confirmed. Pairs enantiomer in the synthesis，their action spectrum character，the melting point and specific rotation etc. Other physcal constants are very good test.Keywords: Chiral Amino Alcohols; Ligand; Identification
