The absolute stereochemistry of the aglycon part of an antitumor antibiotic vicenistatin (1) was determined by a synthetic approach. Two relevant components degradatively derived from natural 1 were compared with the corresponding synthetic standards prepared from known compounds by stereochemically defined chemistry. The absolute configuration of 1 turned out to be 6S,7S,18S.
