Recent advances on oxazolidinones synthesize from carbon dioxide

Carbon dioxide capture and utilization (CCU) is the best way to solve the problem of reducing concentration of carbon dioxide in the atmosphere, and it has a good prospect for development. On this basis, chemical researchers have explored the methods of synthesizing valuable organic compounds with CO₂ as carbon source. The oxazolidinones are commonly used to synthesize drugs, and they are significant in organic synthesis as chiral molecules and intermediates. The synthetic methods of oxazolidinones have emerged in recent years. Furthermore, the methods of using carbon dioxide as a carbon source have attracted many researchers. In earlier years, people explored cycloaddition reactions of carbon dioxide and aziridines to synthesize oxazolidinones, and they took alkali metals, Cr, Al or other metals as catalysts to improve the efficiency of the reactions. Because of the cost and the principle of green synthesis, it is more suitable for large-scale reaction to select cheap and easily available ionic liquids or no catalysts. In addition, carbon dioxide and compounds such as β-amino alcohols, unsaturated amines and 1, 2-dihalohydrogenated compounds can obtain moderate or even excellent yields under different reaction conditions. In this paper, we summarized the synthetic methods of oxazolidinones using CO₂ with different raw materials in recent years.
