Graphical Abstract

Making waste a functionality: Oxidative electron-transfer-mediated anion–radical transformations are rendered catalytic by employing a 2,2,6,6-tetramethyl-N-oxopiperidinium salt and ferrocene. The method provides an asymmetric approach to highly functionalized cyclopentane and pyrrolidine derivatives. At the same time the co-generated reduced species TEMPO serves as a useful oxygenating functionality.

Abstract

Oxidative single-electron transfer-catalyzed tandem reactions consisting of a conjugate addition and a radical cyclization are reported, which incorporate the mandatory terminal oxidant as a functionality into the product.
