Abstract

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)-2- ...
