In relation to the synthesis of the pradimicin-benanomicin antibiotics, a model study was carried out for introducing the disaccharide moiety. The glycosyl donor 2, prepared from D-glucose and D-xylose, was allowed to react with various glycosyl accepters in the presence of Cp2HfCl2 and AgClO4. Also studied was the reactivity difference between the conformers of the trans-phenanthrendiol derivatives 12, 13 and 14. (C) 2000 Elsevier Science Ltd. All rights reserved.
