Popis: A series of novel 3-deoxy-3-des-cladinosyl-6- O -methyl erythromycin A analogues has been synthesized and evaluated in vitro for antibacterial activity. These analogues were readily synthesized by tributyltin hydride-mediated radical reduction of a 3- O -xanthyl intermediate to afford the 3-deoxy macrolide. A number of oxime, carbonate, and carbamate derivatives were synthesized and evaluated for antibacterial activity. Overall, these analogues had fairly good antibacterial activity against gram-positive bacteria, although they were generally less potent than the corresponding 3- O -cladinosyl or 3-keto analogues.
