SiO2-POCl2 Nano-Particles Promoted the Synthesis of Novel Structure of Alkyl 2-oxo-3,4-diaryloxazolidine-5-carboxylate Derivatives

Silica-POCl2 was used as the promoter for the three-component reaction of ethyl/methyl 3-phenyl glycidate, aniline derivatives, and dimethyl carbonate, leads to the synthesis of methyl/ethyl 2-oxo-4-phenyl-3-aryloxazolidine-5-carboxylate derivatives. The desired product was obtained in high yields.
