Cobalt-catalyzed C–H activation and regioselective intermolecular annulation with allenes

Abstract

An efficient Co(<sc>ii</sc>)-catalyzed intermolecular annulation of <italic>N</italic>-(quinolin-8-yl)benzamide with allenes for the synthesis of novel isoquinolin-1(2<italic>H</italic>)-one scaffolds has been developed.
