The invention relates to the field of chemical derivatization. In particular, it relates to modified aminoglycosides, such as antibiotics, and methods for producing them. Provided is a method for the regioselective diazotation of a desoxy-streptamine- substituted aminoglycoside, comprising contacting the aminoglycoside with imidazole- -sulfonyl azide hydrochloride under neutral p H conditions to allow for the conversion of the single amine group at the 3-C position of the desoxy-streptamine ring into an azide group. Also provided are novel antibiotic compounds.
