Abstract
Building blocks of methyl alpha-D-glucopyranoside possessing free hydroxyl functions in the position 2 or 3 and orthogonal acid-labile protecting groups on the other reacting sites can be conveniently prepared by means of benzophenone dimethyl ketal under very mild experimental conditions. Trityl and diphenylmethoxymethyl groups have been easily built on secondary hydroxyl groups of monosaccharides for the first time. (C) 1999 Elsevier Science Ltd.
