  摘要：

  A procedure for the O-benzyloxycarbonylation of secondary alcohols in the glucose, galactose, mannose, ribose and deoxyribose series is described. Starting from the (4-methoxy)tritylated derivatives on the primary hydroxyl group, the fully protected compounds were obtained for the first time in high yields.
