Synthetic studies of erythromycin derivatives. Synthesis and antimicrobial activities of 3''-EPI-erythromycin A and (9S)-11-dehydroxy-9-deoxo-9-hydroxy-11- oxoerythromycin A.
Two new derivatives, 3''-epi-erythromycin A (2) and (9S)-11-dehydroxy-9-deoxo-9-hydroxy-11-oxoerythromycin A (3), have been synthesized by using glycosylation with glycal (Ferrier rearrangement), bromomethoxylation and bis(tributyltin) oxide-bromine oxidation as the key steps. Their antimicrobial activities were compared with those of erythromycin A (1).
