O-Linked glycosylation is one of the most abundant posttranslational modifications of proteins. Within the secretory pathway of higher eukaryotes, the core of these glycans is frequently an N-acetylgalactosamine residue that is α-linked to serine or threo

A new type of phosphate-pyridine (P, N) ligand derived from d-glucosamine and BINOL was synthesized and successfully applied in Cu-catalyzed enantioselective conjugate addition of diethylzinc to chalcones for the first time, high yields and enantioselectivities were obtained when the ligand 10a which contains (S)-BINOL was used. The results also showed that the configuration of BINOL at the ligand backbone had remarkable effects on the activities and enantioselectivities.

UDP-N-acetylmuramic acid (UDP-MurNAc) is a substrate of MurC, an important enzyme in the intracellular pathway of bacterial peptidoglycan biosynthesis. Various approaches towards preparation of UDP-Mur/VAc have been published but these synthetic preparations were shown to include many problematic steps. An optimization study with the focus on muramyl phosphate and UMP-morpholidate coupling was performed, resulting in a synthetic procedure enabling robust and easily reproducible production on a multi-gram scale.
Synthesis of anomerically pure, furanose-free α-benzyl-2-amino-2- deoxy-D-altro- and D-manno-pyranosides and some of their derivatives

The anomerically pure benzyl α-d-glycoside of 2-amino-2-deoxy- mannopyranoside was synthesized from d-glucopyranose via 2-amino-2-deoxy-d- altrose intermediates. Unlike the direct synthesis from mannosamine in the literature, our method provides furanose-

The azidonitration of 3,4,6-tri-O-acetyl-1,5-anhydro-2-deoxy-D-arabino-hex-1-enitol at low temperature afforded preponderantly the azidonitrate having the D-manno configuration.After reaction with sodium acetate, 1,3,4,6-tetra-O-acetyl-2-azido-2-deoxy-α-D-mannopyranose was directly isolated and deblocking gave 2-azido-2-deoxy-D-mannopyranose. 3,4,6-Tri-O-acetyl-2-azido-2-deoxy-α-D-mannopyranosyl bromide and 2-azido-3,4,6-tri-O-benzyl-α-D-mannopyranosyl bromide were prepared and are suitable for selective α- and β-glycoside synthesis.In the presence of platinum-oxygen, the catalytic oxidation of benzyl 2-azido-2-deoxy-α-D-mannopyranoside gave in high yields (benzyl 2-azido-2-deoxy-α-D-mannopyranosid)uronic acid from which 2-amino-2-deoxy-D-mannopyranuronic acid was obtained.By catalytic oxidation, selectively blocked derivatives of 2-amino-2-deoxy-D-mannopyranose were converted into the correspondind uronic acid derivatives.
