| Abstract: | Phosphorylation of 2-arylideneaminophenol with dichlorophenylphosphine in the presence of triethylamine and subsequent treatment with water led to stereoisomeric derivatives of 3-aryl-2-oxo-2-phenylbenzo[e]-1,4,2-oxazaphosphinanes, which were separated by column chromatography to the individual diastereomers. The structure of stereoisomers was established by NMR spectroscopy and X-ray crystallography. |
