Sažetak (engleski)
The configuration of oximes <b>1a</b> and <b>1b</b> was investigated by chemical and spectroscopic methods. Under the Beckmann rearrangement conditions, using sulfonyl chlorides as reagents, the sulfonic esters <b>2a-c</b> were obtained. Under more drastic conditions, using PCl<sub>5</sub> or P<sub>2</sub>O<sub>5</sub>, the only isolated product was 4-nitro-5H-furan-2-on (<b>3</b>). It was also formed as the sole product by hydrolysis of oximes <b>1a-b</b>, as well as sulfonic ester <b>2a</b>. The structure of all compounds was determined by one- and twodimensional homo- and hetero-nuclear <sup>1</sup>H and <sup>13</sup>C NMR correlated spectra: COSY, NOESY, HETCOR and HMBC. Gradient selected differential NOE measurements confirmed that, in dimethylsulfoxide solution, oximes <b>1a</b> and <b>1b</b> exist in <i>E</i>-configuration, irrespective of the route of their formation.
