Reactions of ethyl methylsulfonylpyruvate and its sodium salt with a mixture of aromatic aldehyde and arylamine
Tóm tắt
The reactions of ethyl methylsulfonylpyruvate and its sodium salt with a mixture of aromatic aldehyde and arylamine afforded 1,5-diaryl-3-hydroxy-4-methylsulfonyl-3-pyrrolin-2-ones. The spatial structure of 1,5-diphenyl-3-hydroxy-4-methylsulfonyl-3-pyrrolin-2-one was established by X-ray diffraction analysis.
