Visible-light mediated strategies for the synthesis of nitrogen-based heterocycles

Abstract

Nitrogen-containing molecules are essential to human-life. Their utility spans a range of industries, but its profound significance to the pharmaceutical and chemical biology arenas has ensured the continuous development of modern, sustainable, and more efficient chemical synthesis methods. In this regard, visible-light mediated synthesis has become an indispensable technology. In this review we highlight the key photocatalysis strategies that have enabled the construction of important 4-, 5- and 6-membered nitrogen-containing heterocycles. We hope that this review will serve both a reflective purpose: to pay homage to the powerful nature of photochemical synthesis and its pioneers that have led us this far; and an inspirational purpose: igniting thoughts and visions that lead toward new doors of unchartered activation modes.
