SiO2‐POCl2 nanoparticles promoted the synthesis of novel structure of 2,3‐dihydrooxazole derivatives

Silica‐POCl2 was used as promoter for the three‐component reaction of ethyl 3‐phenyl glycidate, aniline derivatives, and dimethylformamide (DMF), which leads to the synthesis of ethyl 4‐phenyl‐3‐aryl‐2,3‐dihydrooxazole‐5‐carboxylate derivatives. The desired product was obtained in high yields.
