Homocoupling of aldimines mediated by zirconocene: synthesis of vicinal diamines and imidazolidines
摘要:
The reductive coupling of imines in the presence of the lanthanide-originated zirconocene equivalent allows the synthesis of vicinal diamines or imidazolidines under mild conditions in good yields with high diastereoselectivity. (C) 2011 Elsevier Ltd. All rights reserved.
