An efficient method for the large-scale preparation of α-N-acetylglycosaminides, such as fluorogenic TN-antigen probes and an α-GalNAc-Ser derivative, has been achieved using FeCl3-catalyzed one-step condensation between commercially

N-Acetylmuramyl-L-alanyl-D-isoglutamine α-phenylglycoside was synthesized from α-phenyl-D-glucosaminide peracetate, which was obtained by fusing β-D-glucosamine pentaacetate with phenol and zinc chloride followed by deacetylation. α-Phenyl-N-acetylglucosa

Direct and practical anomeric O-arylation of sugar lactols with substituted arylboronic acids has been established. Using copper catalysis at room temperature under an air atmosphere, the protocol proved to be general, and a variety of aryl O-glycosides have been prepared in good to excellent yields. Furthermore, this approach was extended successfully to unprotected carbohydrates, including α-mannose, and it was demonstrated here how the interaction between carbohydrates and boronic acids can be combined with copper catalysis to achieve selective anomeric O-arylation.
Facile synthesis of nitrophenyl 2-acetamido-2-deoxy-α-D- mannopyranosides from ManNAc-oxazoline

The synthetic procedures for a large-scale preparation of o- and p-nitrophenyl 2-acetamido-2-deoxy-α-D-mannopyranoside are described. The synthetic pathway employs the glycosylation of phenol with ManNAc oxazoline, followed by nitration of the aromatic moiety yielding a separable mixture of the o- and p-nitrophenyl derivative in a 2:3 ratio.
