A new approach for the synthesis of tetrasubstituted/functionalized NH-pyrroles from gem-diactivated acrylonitriles and TMSCN has been developed. The strategy utilizes the generation of vic-dinitrile viaMichaeladdition and cyanide-mediated nitrile-to-nitrile cyclocondensation, which proceed in tandem guided by manifold roles of “CN”. An extended application to the production of fused pyrrole has
