Abstract: The title compound, C₆H₉NO₄, was prepared stereoselectively as a precursor for 1-azadienes in a study of hetero-Diels-Alder reactions. The configuration of the C=N double bond was found to be Z, corroborating earlier assignments of similar compounds based only on NMR and IR spectroscopic analysis.
