| dc.description.abstract | The reaction of methyl 3-arylamino-2-benzoylaminopropenoates 2 with phosphorus oxychloride in pyridine at 70°C for 30 min leads to the unexpected formation of N-aryl-N-bis-(5-oxo-2-phenyl-4, 5- dihydro-oxazol-4-ylmethylene) amines 4. In contrast, 4-arylaminomethylene-2-phenyl-2-oxazolin-5-ones 3 are obtained in only 2 min from compounds 2 under similar reaction conditions, which subsequently give compounds 4 on treatment with POCI3 in pyridine. A tentative mechanism to account the following conversion is suggested. | en_US |
