Visible-light induced sustainable photochemical approach for synthesis of spirocyclic compounds

Abstract

The application of photocatalysis in organic synthesis has become essential because it allows for gentle, eco-friendly, and effective transformations into essential molecular scaffolds. A sustainable and effective technique for generating spirocyclic compounds using photocatalysts is carried out via visible light-induced photochemical methods. This method enables the formation of intricate spirocyclic structures using easily accessible starting materials in moderate, eco-friendly conditions.Several visible light mediated spirocyclization involve radical intermediates by a variety of processes, such as hydrogen atom transfer and single-electron transfer. The current developments in photocatalysed synthesis of spirocyclic compounds, has been highlighted.
