Acidic hydrolysis of gentamicin C1 and C1a provides ready access to the pseudodisaccharides gentamineC1 and C1a respectively. Glycosylation of tetrakis-N-benzyloxycarbonylgentamine C1 and C1a using the Koenigs–Knorr or Lemieux–Nagabhushan reactions has led to the preparation of a series of novel 6-O-α- and -β-3-amino-3-deoxy- and 2-amino-2-deoxy-D-hexopyranosyl and hexofuranosyl analogues of the gentamicins
