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.

From Axial Chirality to Central Chiralities: Pinacol Cyclization of 2,2′-Biaryldicarbaldehyde to trans-9,10-Dihydrophenanthrene-9,10-diol
only the trans-diol, and the stereospecificity to transmit the axial chirality (in case the starting biphenyl is configurationally stable) onto two stereogenic centers of the product-characterize the pinacol cyclization of 2,2'-biaryldicarbaldehydes (see reaction). The accessibility of trans-9,10-dihydrophenanthrene-9,10-diols provides the new enantiopure C2 -symmetric diol 1, which shows potential utility
