Stereoselective synthesis of trans-2,3-disubstituted pyrrolidines via addition to N-acyliminium ions
摘要:
An efficient and stereoselective synthesis of trans-2,3-disubstituted pyrrolidines is described. The intermolecular alkylation of racemic N-acyliminium ions generated in situ from the corresponding 3-substituted lactams proceeds stereoselectively and in high yield. (c) 2006 Elsevier Ltd.
