A flexible, unified radical-based approach to polycyclic structures
Abstract
Cis- and trans-decalins, trans-perhydroazulenes, and [5.3.1]-bicyclo- undecanone scaffolds can be readily constructed starting from unsaturated ketones and using the degenerative xanthate transfer technology to accomplish unusual and otherwise difficult radical cyclisations. © 2011 The Royal Society of Chemistry.
