Abstract
beta-Laminaribiose octaacetate (2b) was prepared in greater than 50% yield from the microbial polysaccharide curdlan by specific degradation with a yeast cell-wall lytic enzyme preparation, Kitalase,and subsequent acetylation. Acetolysis of curdlan also gave alpha-laminaribiose octaacetate (2a) in 27% yield. The usefulness of these peracetates 2a and 2b as starting materials for organic synthesis was shown by converting 2b into N-acetylhyalobiuronic acid (23), the disaccharide repeating unit of hyaluronic acid. The conversion was carried out via a series of reactions, which included azidonitration of the glucal derivative and selective alkylidenation or direct tritylation to discriminate two primary hydroxyl groups existing in the disaccharide intermediates.
