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

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.open11119sciescopu
