摘要：
The catalytic activation of pyridines as organocatalysts in the three-component cycloaddition of CO2, propargyl alcohol and primary amine was investigated, and 2,2',2 ''-Terpyridine was found to be the efficient organocatalyst to afford 4-methylene-2-oxazolidinones or 2(3H)-oxazolones in good to high yields. 2,2',2 ''-Terpyridine also showed high catalytic activity in the coupling reaction of CO2 with aziridines bearing either electron-donating or electron-withdrawing N-substituents to give substituted 2-oxazolidinones in high yields.
