Article abstract of DOI:10.1016/S0040-4039(00)60719-0

A new methodology allowing to assemble fused vinylcyclopropanes by cyclization of vinyl radicals is herein reported.This methodology is based on the trapping of the cyclopropylcarbinyl radical intermediate by β-phenylthiyl elimination which provides the v
