The ongoing studies on oligosaccharide synthesis have resulted in the development of
precise synthetic methods by which a large portion of the complex natural oligosaccharides …

A neuritegenic ganglioside from sea cucumber, HLG‐2 (see figure), has been synthesized
for the first time. The unique tandem of sialic acids, Neu5Gc‐α (2, 4)‐NeuAc, was …

Intact and integral glycosylation of membrane-associated as well as secreted glycoproteins
has been shown to be essential for many aspects of the proper function of biological …

The preparation of a crystalline, peracetyl adamantanyl thiosialoside donor protected by an
isothiocyanate group is described. On activation at− 78° C in the presence of typical …

Sialic acid is an important component of cell surface glycans, which are responsible for
many vital body functions and should therefore be thoroughly studied to understand their …

The potential of an N-Troc-protected sialic acid donor, equipped with phenylsulfenyl
functionality as a leaving group, has been explored. As a result, the entitled donor was …

We have developed an efficient methodology for highly stereoselective sialylation using 3-
position substituted sialic acids and have prepared 2a having a 3β-phenylthio group as a …

The first total syntheses of disialoganglioside GD1α and its α2-6 positional isomer are
described. Suitably protected pentasaccharide derivatives, derived from known …

A CH 2-linked α (2, 3) sialylgalactose analogue was efficiently synthesized using an Ireland-
Claisen rearrangement, which was developed recently by our group for constructing a CF 2 …

A stereocontrolled, facile total synthesis of ganglioside GD 3 is described as an example of a
proposed systematic approach to the preparation of gangliosides containing an α-sialyl-(2→ …
