Using allylic azide rearrangement, a convenient method has been developed for the synthesis of 2',3'-dideoxyaminoglycosides that are, otherwise, difficult to be prepared. The antibacterial activity of these novel aminoglycosides also confirms the indispensable role of 2'-NH(2) group for both neomycin and kanamycin classes of aminoglycosides. A novel structural motif containing the hexylaminocarbonyl groups at O-5 and/or O-6 of 2',3'-dideoxyneamine could lead to the production of new aminoglycosides against resistant bacteria.
