Trioxacarcinose B is a unique carbohydrate which has been discovered in antibiotic trioxacarcin A as a component. As a step of total synthesis of the antibiotic, methyl α-trioxacarcinoside B has been synthesized from methyl 2,3-anhydro-6-deoxy-α-l-allo-hexopyranoside by a 7 steps reaction in a yield of 4.3%. The product has been identified by comparison with the authentic sample which was prepared by methanolysis of the antibiotic.
