Erythromycin 9,11-iminoether, as a key intermediate, was obtained through controlling the condition of Beckmann rearrangement of erythromycin A (E) oxime. A stable molecular adduct can be formed from the title compound and acetonitrile with molar ratio of 1∶1. It is a transparent crystal characterized by monoclinic system and P21 space group. Contrasting the crystal structures between the title compound and erythromycin 6,9-iminoether reported in another paper, it would be useful to study the difference between the two isomers and the mechanism of Beckmann rearrangement and isomerization.
