ABSTRACT:
1-N-Alkyl-Aminoglycoside-XK-88 derivatives, valuable as antibacterial agents, are prepared by the reaction of an acid addition salt of the corresponding 1-N-unsubstituted-Aminoglycoside-XK-88 antibacterial derivative or of a 2"-N-alkanoyl-Aminoglycoside-XK-88-5 derivative in an inert solvent, preferably a protic solvent containing water, with one equivalent of a hydride-donor reducing agent and with at least one equivalent of an aldehyde.
The 2"-N-alkanoyl-Aminoglycoside-XK-88-5 intermediates are prepared by the reaction of a partially neutralized acid addition salt of Aminoglycoside-XK-88-5 with an acylating agent, and isolating the 2"-N-alkanoyl-Aminoglycoside-XK-88-5.
