Pd-catalyzed cascade allylic alkylation and dearomatization reactions of indoles with vinyloxirane

Abstract

We have developed Pd-catalyzed intermolecular Friedel–Crafts-type allylic alkylation and allylic dearomatization reactions of substituted indoles bearing a nucleophilic group with vinyloxirane, providing an efficient method to synthesize structurally diverse tetrahydrocarboline and spiroindolenine derivatives under mild conditions.
