    • New compounds, 6"-deoxydibekacin, 4", 6"-dideoxydibekacin, 1-N-(L-4-amino-2-hydroxybutyryl)-6"-deoxydibekacin and 1-N-(L-4-amino-2-hydroxybutyryl)-4",6"-dideoxydibekacin are now produced semi-synthetically from dibekacin, i.e. 3',4'-dideoxykanamycin B. These four new compounds are each useful as an antibacterial agent. Production of 6"-deoxydibekacin or 4",6"-dideoxydibekacin is made by removal of the 6"-hydroxyl group or by removal of the 4"- and 6"-hydroxyl groups from an amino-protected and hydroxyl-protected derivative of dibekacin. Production of 1-N-(L-4-amino-2-hydroxybutyryl)-6"-deoxydibekacin or -4",6"-dideoxydibekacin is made by acylating the 1-amino group of 6"-deoxydibekacin or 4",6"-dideoxydibekacin with the L-4-amino-2-hydroxybutyryl group, or alternatively by removal of the 6"-hydroxyl group or the 4"- and 6"-hydroxyl groups from a known compound, 1-N-(L-4-amino-2-hydroxybutyryl)-dibekacin.
