The first asymmetric synthesis of Kelatorphan-like enkephalinase inhibitor (1S,2R,2′S)-2-[2′-(N-hydroxycarbamoylmethyl)-3′-phenylpropionylamino]cyclohexane-1-carboxylic acid is achieved using lithium amide (R)-5 and pyrrolidinone auxiliary (R)-6; the pyrrolidinone auxiliary is used to create (2S)-benzylsuccinic acid derivative (S)-4 while lithium amide (R)-5 is used to synthesize tert-butyl (1S,2R
使用酰胺锂实现Kelatorphan样脑啡肽酶抑制剂(1 S,2 R,2 'S)-2- [2'-(N-羟基氨基甲酰基甲基)-3'-苯基丙酰氨基]环己烷-1-羧酸的首次不对称合成(R)-5和吡咯烷酮助剂(R)-6; 吡咯烷酮助剂用于生成(2 S)-苄基琥珀酸衍生物(S)-4,而酰胺锂(R)-5用于合成叔丁基(1 S,2 R)-2-氨基环己烷羧酸酯3。
