Recent advances in visible-light-driven photocatalytic synthesis of biologically active N-heterocycles

Heterocycles that contain nitrogen are a very significant class of chemicals that are employed extensively in medicinal chemistry, agrochemistry, and materials research. Thus, there is increasing interest in developing practical, effective, and eco-friendly synthetic processes for creating nitrogen-containing heterocycles. Using visible light as a catalyst for chemical reactions has drawn a lot of attention in recent years because of its inherent abundance, ease of use, and potential industrial applications. Based on the size and kind of N-heterocyclic rings that are produced, this article provides an overview of the synthesis of N-heterocycles utilising visible-light photoredox catalysis.
