The first total synthesis of the antibiotic (−)-hygromycin A (1) has been achieved by a coupling reaction of the sugar moiety (2) and the cyclitol moiety (3). Both components were synthesized in homochiral forms starting from D-glucose. This synthesis fully confirmed the unique structure of 1, which is much different from other usual aminocyclitol antibiotics.
