SYNTHESIS OF A MANNOTETRAOSE—THE REPEATING UNIT OF THE CELL-WALL MANNANS OF MICROSPORUM GYPSEUM AND RELATED SPECIES OF TRYCHOPHYTON
摘要:
A tetrasaccharide, alpha -D-mannopyranosyl-(1 -->2)-alpha -D-mannopyranosyl-(1 -->6)-alpha -D-mannopyranosyl-(1 -->6)-D-maanopyranose (1), the repeating unit of the cell-wall mannans of Microsporum gypseum and related species of Trychophyton, was synthesized using 6-O-acetyl-2,3,4-tri-O-benzoyl-alpha -D-mannopyranosyl trichloroacetimidate (5) and 2-O-acetyl-3,4,6-tri-O-benzoyl-alpha -D-mannopyranosyl trichloroacetimidate (13) as the glycosyl donors in "the inverse Schmidt 'procedure.

An efficient 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.
