A simple and efficient iron-catalyzed intramolecular hydroamination of unactivated olefins

Abstract

(Chemical Equation Presented) A new catalytic activity of iron salts for intramolecular hydroamination is revealed. A number of aminoolefins underwent the reaction under mild conditions to form the corresponding pyrrolidine derivatives in good yield. The reaction displayed good functional-group compatibility and resistance to air and moisture. (Ts = e-toluenesulfonyl). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
