Synthesis of 2-Oxazolidinones from CO2 and 1,2-Aminoalcohols Catalyzed by n-Bu2SnO

The dehydrative condensation of 1,2-aminoalcohols with CO2 is found to proceed in NMP as solvent; 2-oxazolidinones are obtained in the yields of 53-94% when a commercially available tin compound, n-Bu2SnO is used as catalyst.
