Abstract:
The application of photocatalysis in organic synthesis has become essential because it enables mild, eco-friendly, and effective transformations to access 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 under moderate, eco-friendly conditions. Several visible light mediated spirocyclization reactions proceed via radical intermediates through a variety of processes, such as hydrogen atom transfer and single-electron transfer. The current developments in photocatalysed synthesis of spirocyclic compounds have been highlighted.
