Methylenecyclopropanes that on ring opening form unstabilized or electron-rich radicals effect methylenecyclopentane annulations of electron-poor alkenes in good yields with thiyl-radical catalysis. Similar vinylcyclopropane-based annulations involving unstabilized radicals can also succeed under stannyl-radical catalysis.
