On May 18, 2018, Guchhait, Sankar K.; Sisodiya, Shailendra; Saini, Meenu; Shah, Yesha V.; Kumar, Gulshan; Daniel, Divine P.; Hura, Neha; Chaudhary, Vikas published an article.Application In Synthesis of 2-((1H-Indol-3-yl)methylene)malononitrile The title of the article was Synthesis of Polyfunctionalized Pyrroles via a Tandem Reaction of Michael Addition and Intramolecular Cyanide-Mediated Nitrile-to-Nitrile Condensation. And the article contained the following:
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 via Michael addition 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 also been realized. The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).Application In Synthesis of 2-((1H-Indol-3-yl)methylene)malononitrile
