Organocatalysis for the Chemical Fixation of Carbon Dioxide to Synthesise N-Heterocycles

Abstract

Organocatalysed reactions are becoming powerful tools in the construction of complex molecular skeletons. It gains extra importance when used as a chemical approach to the chemical fixation of carbon dioxide (CO2). Carbon dioxide is an increasingly dangerous environmental hazard as the global climate temperature rises through the greenhouse effect. Meanwhile, in the past decades, significant advances can be noted in the use of organocatalysis for CO2 capture and its conversion into valuable chemicals. Therefore, herein we review a full set of organocatalysts used in CO2 fixation for the synthesis of N-heterocycles since they are present in several chemical structures with biological relevance.
