The role of N‐glycans in the secretion of glycoproteins by suspension‐cultured sycamore cells was studied. The transport of glycoproteins to the extracellular compartment was investigated in the presence of a glycan‐processing inhibitor, castanospermine. Castanospermine has been selected because it

✦ Synopsis
The stereoselective syntheses of one pentasaccharide and one tetrasaccharide containing the Glc-a-(1 ~ 3)-Man-a moiety as their terminal unit, as well as one tetrasaccharide and one trisaccharide containing the Man-a-(1 ---, 2)-Man-a terminal unit were accomplished through the utilization of two key glycosyl donors, namely, 4-pentenyl 3-O-acetyl-2,4,6-tri-O-benzyl-a-Dmannopyranoside and ethyl 2- O-acetyl-3,4,6-tri-O-benzyl-l-thio-a-D-mannopyranoside.
