The indolo[2,3-a]carbazole glycosides are potent antitumor antibiotics currently undergoing clinical trials for the treatment of numerous types of cancer. AT2433-A1 is the most complex member of this family of compounds possessing a unique disaccharide with a sensitive aminodeoxysugar and an unsymmetric aglycon. The synthesis of this naturalproduct requires a method for glycosylation that sets the
