University of the Pacific Theses and Dissertations
The present work consists of two parts. The first part contains the synthesis of 3,4,6-tri-o-benzoyl-D-glucopyranosido-[1,2:41,51]-21-oxazolidone (III) and the study of its chemistry in order to determine whether it could be used as a simultaneous protecting group for C1 and C2 in the preparation of new aminosugars. The second part covers the synthesis and de-o-benzoylation of β-D-glucosaminides. The products thus obtained can be used to prepare new disaccharides. In addition new aminosugar derivatives have been prepared.

The objectives of this research problem were divided into several parts. The first objective was to develop a practical method of preparing 2,6-diamino-2,6-dideoxy-galactose. A second objective was to investigate the derivatives of benzyl-N-carbobenzoxy-α-D-galactosaminide. FInally, the third objective was to lay the groundwork for another possible route for the synthesis of 2,6-diamino-2,6-dideoxy-galactose other than the uronic acid route.
