title: Synthesis of lactams by radical substitution reaction of alpha,beta-unsaturated acyl radicals at amine nitrogen.
abstract: [reaction: see text] Substitution at nitrogen by alpha,beta-unsaturated acyl radicals took place accompanied by elimination of an alpha-phenethyl radical. This reaction led to the development of a new carbonylative annulation method for five- to seven-membered ring lactams.
