Synthesis of Enantiopure 3-Substituted Morpholines
摘要:
Enantiopure 3-substituted morpholines were assembled through ring-opening of a N-2-benzothiazolesulfonyl (Bts) activated aziridine with organocuprates followed by a ring annulation reaction with a vinylsulfonium salt under microwave conditions. Deprotection of the N-Bts group proceeds under very mild conditions with 2-mercaptoacetic acid and LiOH at rt.

Heterocyclic pentafluorophenyl sulfonate esters are shelf stable alternatives to the often less stable sulfonyl chlorides. They are easily prepared from thiols and react readily with primary and secondary amines to produce sulfonamides in high yields. (c) 2009 Elsevier Ltd. All rights reserved.
