Palladium-catalyzed inter- and intramolecular hydroamination of styrenes coupled with alcohol oxidation using N-fluorobenzenesulfonimide as the oxidant
摘要:
Palladium-catalyzed inter- and intramolecular hydroaminations of styrenes that are coupled to alcohol oxidation under oxidative condition are reported. The fluorination reagent NFSI is used as the nitrogen source as well as the oxidant. Bidental nitrogen ligand bathocuproine plays a crucial role in this transformation. (C) 2010 Elsevier B.V.

An efficient syntheticroute to pyrrolidines that relies on AuCl/AgOTf-catalyzed tandem amination/ringexpansion of substituted cyclopropyl methanols with sulfonamides is reported herein. The reactions proceed rapidly at 100 degrees C with catalyst loadings as low as 2 mol % and produce the pyrrolidine products in yields of 30-95 %. The method was shown to be applicable to a broad range of cyclopropyl
