N-meth-acryloyl-α-amino acids, new isomerized oxazolones were obtained. By NMR spectroscopy, the structures of isomerized oxazolones were determined to be pseudoxazolones (2-isopropylidene-4-alkyl-3-oxazolin-5-ones). The NMR spectra of several pseudoxazolones were measured and compared with the normal oxazolones.
