Total Synthesis of (±)-Stemonamide and (±)-Isostemonamide Using a Radical Cascade
摘要:
Total synthesis of stemonamide and isostemonamide is described. The concise construction of the tricyclic core of these alkaloids was achieved by radical cascade involving 7-endo and 5-endo cyclizations.

A total synthesis of (+/-)-stemonamide and (+/-)-isostemonamide has been achieved by using a radical cascade that involves two endo-selective cyclizations. (+/-)-Stemonamine and (+/-)-isostemonamine are synthesized by chemoselective reduction of (+/-)-stemonamide and (+/-)-isostemonamide, respectively. (C) 2008 Elsevier Ltd. All rights reserved.
