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

Abstract

Alkylidenecyclopropanes undergo Mn(OAc)3-mediated addition with malonate, leading to dihydronaphthalene derivatives in moderate yields.
