Kanamycins A and B react with a variety of water-soluble pyrylium ions in aqueous solution specifically at the 6′-primary-alkyl primary amine functions to give the corresponding pyridinium ions in high yield. Neomycin also reacts at only one amino group. Products were characterised by 13C n.m.r. and elemental analysis.
