Cis-3-hydroxy-5-phenyl pyrrolidine could be synthesized stereoselectively from inexpensive starting materials, (R)-(+)-ethyl-4-chloro-3-hydroxybutanoate and (R)-(+)-4-chloro-3-hydroxybutyronitrile. Key feature involves face- and chemo-selective hydrogenation of cyclic imine 5 as the common key intermediate using Pt/C catalyst. Transformations described here will allow a practical synthesis of novel carbapenems, 1 and 2.
