✦ Synopsis


Among the semisynthetlo derivative8 of an importent antibiotio, erythrunytin A, Its cyclic carbonate exhibit8 the unique property of being more active against becteria than the parent antibiotic l,B . In the hypothetical struoture of the canpound pO8tUlated by Eli Lilly group, the substitution by carbonate moiety occurred at 9 and 11 oarbon atams of the macrolide ring'.

## Abstract A complete and unambiguous assignment of the ^1^H and ^13^C NMR spectra of (__E__)‐erythromycin A oxime in acetone‐__d__~6~ was accomplished by two‐dimensional chemical shift correlation methods. The ^1^H NMR NOE data, in conjunction with molecular modeling techniques, were used to pred
