First tandem free-radical cyclization reaction of alkylenecyclopropanes: a novel and efficient method for the preparation of 2-(3,4-dihydronaphthalen-2-yl)malonic acid diethyl esters.
Alkylidenecyclopropanes undergo Mn(OAc)3-mediated addition with malonate, leading to dihydronaphthalene derivatives in moderate yields.
