Key Points

The method improves the activation of sp³-carbons, providing new pathways for chemical synthesis.
Key findings show that visible light promotes tandem C–H activation along with N-alkylation.
Observational analysis reveals the role of n-heterocyclic carbenes in enhancing reactivity using single-electron transfer.
This work supports innovative strategies in organocatalysis, highlighting potential for broader applications in organic synthesis.

Implication

This research demonstrates visible-light driven C–H activation and N-alkylation in tetrahydroisoquinolines, indicating a novel photocatalytic approach.

Abstract

While N-heterocyclic carbenes (NHCs) have played a vital role as organocatalysts due to their Umpolung reactivity toward carbonyl or imine carbons, activation of sp³-carbons via single-electron transfer (SET) processes remains...
