An efficient methodology for the stereoselective synthesis of cis‐2,5‐disubstituted pyrrolidines using copper catalyst was developed. The corresponding cis‐2,5‐disubstituted pyrrolidines could be obtained in reasonable yields and with good stereoselectivities in the presence of 4,4′‐di‐tert‐butyl‐2,2′‐bipyridine as ligand and 1‐methyl‐2‐pyrrolidinone as solvent.
开发了一种使用铜催化剂立体选择性合成顺式-2,5-二取代吡咯烷的有效方法。在4,4'-二叔丁基-2,2'-联吡啶作为配体和1-甲基-2-基吡啶存在下,可以以合理的收率和良好的立体选择性获得相应的顺式-2,5-二取代的吡咯烷。吡咯烷酮作为溶剂。
