Abstract
New compound, 3',4'-dideoxy-3'-fluorokanamycin B is now provided, which is useful as antibacterial agent. 3',4'-Dideoxy-3'-fluorokanamycin B is prepared by a process comprising halogenating an N,O-protected derivative of 3'-deoxy-3'-fluoro-4'-O-sulfonylkanamycin B with a metal halide, reducing the resulting 4'- halogenated 3'-deoxy-3'-fluorokanamycin B derivative to convert its 4'-halo group into a hydrogen atom, and thereby to produce an N,O-protected derivative of 3',4'-dideoxy-3'-fluorokanamycin B, and removing the remaining amino-protecting groups and the remaining hydroxyl-protecting groups from the reduction product by conventional deprotecting methods.
