Abstract
A novel strategy is described in which an intermolecular carbon-centered ra dical addition to a beta -oxygenated acceptor followed by intramolecular cy clization leads to the formation of 2,3,4- and 2,3,4,5-substituted furan ri ngs. Excellent levels of 2,4-trans selectivity are observed in accordance w ith the Beckwith-Houk model for selectivity in 5-exo radical cyclizations.
