Total Synthesis of Angucyclines. XVII. First Synthesis of Antibiotic 100-1, a Deoxydisaccharide Angucycline Antibiotic of the Urdamycinone B-Type

Two routes to the deoxydisaccharide angucycline antibiotic 100-1 (3) are described. Key steps comprise the regioselective oxidation/bromination of the 1,5-diacetoxy-olivose C-saccharide 7 to the bromoquinone 8. Diels-Alder reaction of the bromoquinone wit
