A novel group of aminoglycosides which share some structural features of currently available aminoglycosides with regard to the backbone, while also having significant structural differences. The similarity enables these aminoglycosides to be highly potent and effective antibiotics, while the significant differences enable these aminoglycosides to reduce or even block antibiotic resistance.

An improved method for the synthesis of azides is described. Diazotransfer from trifly azide effectively with Cu++, Ni++ or Zn++ as a catalyst. The process is amenable to scaleup, can be carried out using commercially available reagents and does not require anhydrous conditions. When metals are scavenged from the reaction, the rate drops by many orders of magnitude.

The conversion of selectively protected gentamicin and sisomicin derivatives into the 1- and 3-oxo-compounds by reaction with 3,5-di-t-butyl-1,2-benzoquinone is described. By application of suitable reductive techniques these oxo-aminoglycosides have been converted into novel 1- and 3-epi-, 1- and 3-deamino-1- and -3-hydroxy-, 1- and 3-deamino-1- and -3-epi-hydroxy-, and 1-deamino-derivatives.
