Overview

Photocatalytic method diversifies unactivated alkenes into N-heterocycles in water, highlighting efficiency and simplicity.

Key Points

  • The study aims to develop a photocatalytic strategy for synthesizing N-heterocycles using water as a medium.
  • Utilized a tetrabutylammonium decatungstate/persulfate catalytic system under near-UV irradiation
  • Incorporated PEG-600 in the reaction
  • Conducted mechanistic studies to understand the decarboxylative cyclization process
  • Demonstrated effective synthesis of 3-substituted indolines, tetrahydroquinolines, and dihydroquinolinones
  • Showed temperature and operational simplicity under mild conditions
  • Achieved late-stage diversification of theophylline and successful gram-scale preparation.
