A route to synthesize 3-aryl-2-oxazolidinones is developed, which is achieved through a three component reaction between CO2, aryl amines, and epoxides with a binary organocatalytic system composed of organocatalysts and DBU (1,8-diazabicyclo[5.4.0]undec-7-ene). The method allows wide scopes of epoxide and aryl amine substrates with various functional groups under mild reaction conditions. The control experiments indicate that a cyclic carbonate is formed via cycloaddition of epoxides with CO2, which further reacts with the β-amino alcohol originating from epoxides and aryl amines, resulting in the formation of 3-aryl-2-oxazolidinones finally.

A straightforward method to construct oxazolidinones through a three-component reaction involving CO2, epoxides, and amines promoted by a combination of Bu4NI and 1,8-diazabicyclo[5.4.0]undec-7-ene was developed. A wide range of aromatic and aliphatic amines and monosubstituted epoxides were converted into 3,5-disubstituted-2-oxazolidines in up to 95 % yield. This metal-free and easily available catalytic system was applicable to a broad range of substrates, including conventionally challenging ones such as aliphatic epoxides, at atmospheric pressure. Preliminary mechanistic studies suggested a reaction pathway involving β-amino alcohols.
