ABSTRACT:
A new deoxystreptamine-containing aminoglycoside antibiotic derivative in which all the amino groups other than the amino group at the 1-position of the deoxystreptamine moiety are formylated is obtained in a high yield by treating a deoxystreptamine-containing aminoglycoside antibiotic derivative in which all the amino groups are formylated with a basic substance. The new derivatives are very important for production of 1-N-modified deoxystreptamine-containing aminoglycoside antibiotics.
