Photocatalytic Isocyanide-Based Multicomponent Domino Cascade toward the Stereoselective Formation of Iminofurans

摘要

A visible-light-promoted three-component isocyanide-based synthesis of iminofurans is herein reported. The reaction proved to be general in scope and proceeds through a triple domino process. Control experiments with O-18-labeled water and TEMPO provided key mechanistic insights for delineating the reactivity paradigms crucial to design efficient photoredox isocyanide-based domino transformations.
