Cycloaddition reactions are notable as one of the most important reaction classes in chemical synthesis due to their ability to generate polycyclic compounds in a single step using straightforward and easily accessible starting materials. In recent times, visible-light-mediated photocatalysis has emerged as a powerful tool for enabling a wide range of transformations.
