The derivatives of (9S)-9-hydroxyl-12-methylene erythromycin A were synthesized by using erythromycin A as a starting material. An intermediate (9S)-9, 11-O-isopropylidene-6-0-allyl-2', 4 ''-0-bis (benzoyl)-12, 21-anhydro erythromycin A 12 was obtained. The antibacterial activity in vitro of two compounds, 6 and 11, was tested. The preliminary biological test showed that two compounds exhibited less potent antibacterial activity in vitro.
