摘    要:用(S)-Ru(BINAP)Cl2]2(NEt3)作催化剂,不对称氢化还原(4-氯苯基)-(吡啶-2-基)-甲酮得到(S)-(+)-(4-氯苯基)-(吡啶-2-基)-甲醇,与4-(4-溴哌啶-1-基)丁酸乙酯缩合,再经水解、成盐得到抗过敏药苯磺酸贝他斯汀,总收率57%。

关 键 词:苯磺酸贝他斯汀  抗过敏药  不对称合成

Abstract:Bepotastine besilate was synthesized from (4-chlorophenyl)-(pyridine-2-yl)-methanone by asymmetric hydrogenation with (S)-Ru(BINAP)Cl2]2(NEt3) as the catalyst to give (S)-(+)-(4-chlorophenyl)-(pyridine-2-yl)-methanol, which was subjected to condensation with ethyl 4-(4-bromopiperidin-1-yl)butyrate followed by hydrolysis and salification with an overall yield of 57%.
Keywords:bepotastine besilate  antiallergic agent  asymmetry synthesis
