Abstract
The exploitation of alkoxy radicals derived from 1-ethenylcycloalkanols for use in a two- carbon ring expansion protocol was proposed. Direct one-pot alkoxy radical-mediated fragmentation-cyclization was not feasible since the reactive intermediate was quenched by iodine in the reaction mixture. However, via the use of iodo epoxides 3, the tandem fragmentation-cyclization sequence could be accomplished. This afforded ring-expanded ...
