Radical Cyclisations of Methylenecyclopropane Derivatives
Radical cyclisations of various methylenecyclopropane derivatives have been studied and it has been found that methylenecyclopropyl propyl radicals undergo exclusive 5-exo cyclisation while methylenecyclopropyl butyl radicals give a mixture of products re

Alkyl radical cyclisations of methylenecyclopropane derivatives
Radical cyclisations of various methylenecyclopropane derivatives have been studied. Cyclisation of diphenylsubstituted (methylenecyclopropyl)butyl radical 10 gave the unexpected cyclohexene 5, via a series of radical rearrangements. In further studies, (

A Novel Sequence of Radical Rearrangements involving the 5-Exo Cyclisation of a 3-(Methylenecyclopropyl)propyl Radical
Radical 10, generated from the corresponding imidazolethiocarbonyl derivative 3 or the phenyl selenide 4, rearranges in a six-step process to give the cyclohexene 5, after reduction; this rearrangement sequence includes the selective 5-Exo cyclisation of
