A series of the derivatives of chondroitin sulfate E (CS-E) disaccharide repeating unit were prepared by postglycosylation–oxidation strategy. The strategy showed excellent performance in glycosylation both on the reactivity and stereoselectivity. Different protecting methodologies were used for the manipulation of disaccharide building blocks. Substitutes at C-4 of glucosyl donors mildly influenced the glycosylation. The current synthesis afforded a feasible approach for the preparation of CS-E repeating unit.
A robust synthesis of N-glycolyl muramyl dipeptide via azidonitration/reduction

, p. 1515 - 1520 (2015/01/30)
A novel synthetic route leading to N-glycolyl muramyl dipeptide (MDP), a bacterial glycopeptide of particular interest in studies of nucleotide-binding oligomerization domain-containing protein 2 (NOD2), is described. The synthetic strategy hinges on the alkylation of benzylidene-protected glucal with 2-bromopropionic acid and thus circumvents a challenging and non-reproducible SN2 step at the C-3 position of glucosamine derivatives. The subsequent sequence includes an azidonitration and an unusual azide reduction/acylation step via an aza ylide/oxaphospholidine intermediate. This approach generates a protected N-glycolyl MDP that can be either subjected to a one-step global deprotection or differentially deprotected to obtain further derivatives.

experimental part, p. 2746 - 2751 (2009/04/07)
The first stereoselective synthesis of a unique trisaccharide containing an open-chain glycosyl cyclic acetal moiety found in the cell wall of Proteus has been successfully achieved. Most of the intermediate steps are high yielding and highly reproducible. The acetal linkage of the open-chain d-galactosamine moiety with an (S)-configuration was formed exclusively.
