D-mannopyranoside (8) were rapidly synthesizedfrom unprotected methyl beta-D-mannopyranoside (12). Methyl (2-deoxy-2-fluoro-alpha-D-mannopyranosyl)-(1-->3)-[(alpha-D-mannopyranosyl)-(1--> 6)]-beta-D-mannopyranoside (7) and methyl (alpha-D-mannopyranosyl)-(1-->3)-[(2-deoxy-2-fluoro-alpha-D-mannopyranosyl)-(1--> 6)]-beta-D-mannopyranoside (9) were synthesizedfrom the common orthogonally protected precursor
