Abstract
Dehydroxylation of aminoglycoside antibiotics is carried out by halogenation of phosphorylated aminoglycoside antibiotics followed by reduction of thus halogenated antibiotics. The dehydroxylation process is entirely new and gives the final product in a high yield. The resulting deoxyaminoglycoside antibiotics are effective against microorganisms including aminoglycoside antiobiotics-resistant microorganisms.
