Facile synthesis of a comb-like mannohexaose: a trimer of the disaccharide repeating unit of the cell-wall mannans of Aphanoascus mephitatus and related species

摘要

Anefficient method for the preparation of a comb-like mannohexaose having #alpha#-(1->6) and #alpha#-(1->2) linkages has been described using 6-O-acetyl-2-O-benzoyl-3,4-di-O-benzyl-#alpha#-D-mannopyranosyl trichloroacetimidate as the key glycosyl donor in an 'inverse Schmidt' procedure.
