Chemical fixation of carbon dioxide by copper catalyzed multicomponent reactions for oxazolidinedione syntheses

Abstract

The quest to reduce greenhouse gases has triggered the development of new chemical fixation of carbon dioxide. Given the importance of CO₂ based transformation chemistry, we demonstrate the fixation of CO₂ for oxazolidinedione synthesis via a novel multicomponent synthesis. In the presence of a catalytic amount of Cu₂O, various 2-bromo-3-phenylacrylic acid derivatives reacted with CO₂ and amines are transformed to the corresponding oxazolidinedione derivatives in high yields.
