metal-catalyzed C–C bond-forming reactions, and provides an efficient entry to isoindolinone ring systems structurally related to several indolizidine alkaloid frameworks. Acylation of 4-alkylpyridines with 2-iodobenzoyl chlorides under basic conditions results in pyridine dearomatization viaformation of 4-alkylidene dihydropyridines. These reasonably stable intermediates are further transformed through
