Abstract
Deoxyaminoglycoside antibiotics are prepared in a high yield from phosphorylated aminoglycosides by reacting a phosphorylated aminoglycoside (a) with a silylating agent, or (b) successively with (i) a silylating or acylating agent and (ii) a halogenating agent; then subjecting thus obtained intermediate to reduction. Deoxyaminoglycoside antibiotics are useful for treating infections caused by microorganisms which are resistant or non-resistant to the corresponding aminoglycoside antibiotics.
