Dehydrative synthesis of oxazolidinones from amino alcohols and CO2 was achieved in the presence of alkalimetal carbonates such as Cs2CO3 as catalyst. It is noteworthy that 1 atm of CO2 is enough for the reaction to proceed and no special dehydrating agent is required in this system. A mechanstic study showed that the OH of amino alcohol acts as nucleophile and the OH in the carbamic acid moiety is
在碱金属碳酸盐如Cs 2 CO 3作为催化剂的存在下,由氨基醇和CO 2脱水合成了恶唑烷酮。值得注意的是,1atm的CO 2足以进行反应,并且在该系统中不需要特殊的脱水剂。力学研究表明,氨基醇的OH充当亲核试剂,氨基甲酸部分中的OH在环化过程中释放出来。
Catalytic fluoride triggers dehydrative oxazolidinone synthesis from CO<sub>2</sub>

Herein, catalytic fluoride (F−) is demonstrated to be a trigger for dehydrative immobilization of atmospheric pressure CO2, such that reaction of CO2 with β-amino alcohols derived from natural amino acids gives optically pure oxazolidinones in high yields. A synergistic combination of fluoride and organosilicon agents (e.g., Bu4NF + Ph3SiF or siloxanes) enhances the catalytic activity and functional group compatibility. This system lies at the interface between homogenous and heterogeneous catalysis, and may prove useful for the development of recoverable/reusable siloxane-based CO2 immobilization materials.
