title: [Synthesis of derivatives of (9S) -9-hydroxyl-12-methylene erythromycin A and their antibacterial activity in vitro].
abstract: 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-O-allyl-2' ,4"-O-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.
