Spirocyclizative Remote Arylcarboxylation of Non-Activated Arenes with CO2 via Visible-Light-Induced Reductive Dearomatization

Authors

Abstract

Visible-light-induced reductive dearomatization of non-activated arenes is a very challenging transformation and remains in its infancy. Herein, we report a novel strategy to achieve a visible-light-induced spirocyclizative remote arylcarboxylation of non-activated arenes including naphthalenyl- and phenyl-bearing aromatics with CO2 under mild conditions through a radical-polar crossover cascade (RPCC). This reductive dearomatization protocol rapidly delivers a broad range of spirocyclic and valuable carboxylic acid derivatives from readily accessible aromatic precursors with generally good regioselectivity and chemoselectivity.
