title: Synthesis and antibacterial activity of O-methyl derivatives of azalide antibiotics: II. 6-OME derivatives via clarithromycin.
abstract: Direct O-methylation of various derivatives of 9-deoxo-8a- and 9a-aza-8a-homo-erythromycin (2',3'-bis-Cbz protected) gives 6-OMe derivatives only in a small number of special cases. The 6-OMe-azalides can, however, be synthesized beginning from clarithromycin.
