Copper-catalyzed intramolecular hydroamination of allenylamines to 3-pyrrolines or 2-alkenylpyrrolidines
摘要:
Copper salts, such as CuCl, Cul, CuCl2 and Cu(OTf)(2), were used to catalyze the intramolecular hydroamination of allenylamines to provide the corresponding 3-pyrrolines or 2-alkenylpyrrolidines. (C) 2008 Elsevier Ltd. All rights reserved.
