Advances in photochemical/electrochemical synthesis of heterocyclic compounds from carbon dioxide

Abstract

The primary greenhouse gas is carbon dioxide (CO2), which also serves as an excellent C1 building block for the synthesis of heterocyclic compounds. The preparation and transformation of these structures have long been a focus in organic chemistry, making the utilization of CO2 highly advantageous. This paper reviews progress in photochemical/electrochemical construction of heterocyclic compounds using CO2, differentiating between various reaction types and elucidating their underlying mechanisms as well as potential applications.
