ABSTRACT
A novel series of 10-hydroxyl ketolide derivatives were synthesized, during which a distinctive intermediate, 3-O-descladinosyl-3-oxo-11-deoxy-10,11-epoxy-6-O-methylerythromycin A, was obtained from 6-O-methylerythromycin A. The structure and stereochemistry of this novel structure were confirmed via NMR and X-ray crystallography. Moreover, antibacterial evaluations were established in order to assess our modifications and acquire a deep understanding of the ketolides' structure-activity relationship (SAR).
