Redox-neutral zinc-catalyzed cascade [1,4]-H shift/annulation of diaziridines with donor–acceptor aziridines

Abstract

The coupling of diaziridines with donor–acceptor aziridines (DAAs) has been achieved using Zn-catalysis to furnish imidazopyrazole-4,4-dicarboxylates via [1,4]-hydride shift. The use of Zn-catalysis, [1,4]-hydride shift, natural product modification and a late-stage molecular docking study are important practical features.
