A series of carboxyl group or hydroxyl group functionalized organocatalysts were synthesized and applied in three component reaction of carbon dioxide with epoxide, and aryl amines for the synthesis of 3-aryl-2-oxazolidinones. The method allows the reaction to proceed smoothly in the mild reaction conditions, together with excellent substrates scope of epoxides and aryl amines. The control experiments suggest that the cyclic carbonates are formed by the coupling of epoxides with carbon dioxide, which further react with the amino alcohol generated from epoxides and aryl amines, finally resulting in the desired products.

Key words: organocatalyst, carbon dioxide, oxazolidinones, epoxide
