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.
