cyclohexane ring by a combination of freeradical and ionic reactions sequences was achieved. Freeradical alkylation of the remote nonactivated delta-carbon atom involves addition of delta-carbon radicals, generated by 1,5-hydrogen transfer in alkoxy radical intermediates, to radicophilic olefins, while the polar sequence involves enolate anions as intermediates which undergo a cycloalkylation reaction. Thus
