Facile chemoenzymatic synthesis of Lewis a (Lea) antigen in gram-scale and sialyl Lewis a (sLea) antigens containing diverse sialic acid forms

An efficient streamlined chemoenzymatic approach has been developed for gram-scale synthesis of Lewis a angtigen (LeaβProN3) and a library of sialyl Lewis a antigens (sLeaβProN3) containing different sialic acid forms. Intially, commercially available inexpensive N-acetylglucosamine (GlcNAc) was converted to its N′-glycosyl p-toluenesulfonohydrazide in one step. Followed by chemical glycosylation, GlcNAcβProN3 was synthesized using this protecting group-free method in high yield (82%). Sequential one-pot multienzyme (OPME) β1–3-galactosylation of GlcNAcβProN3 followed by OPME α1–4-fucosylation reactions produced target LeaβProN3 in gram-scale. Structurally diverse sialic acid forms was successfully introduced using a OPME sialylation reation containing a CMP-sialic acid synthetase and Pasteurella multocida α2–3-sialyltransferase 1 (PmST1) mutant PmST1 M144D with or without a sialic acid aldolase to form sLeaβProN3 containing naturally occurring or non-natural sialic acid forms in preparative scales.

Generation of a glycosylated asparagine residue through chemoselective acylation of a glycosylhydrazide

Herein, we report the first selective anomeric N-acylation of a glycosylhydrazide. We show that this transformation can be harnessed to generate amino acid building blocks including FmocAsn(GlcNAc)OH (1), a residue that has been previously shown to be a c

Protecting-group-free synthesis of glycosyl 1-phosphates

Glycosyl 1-phosphates enriched in the α-anomer are obtained without the use of protecting groups in two steps starting from the free hemiacetal. Condensation of free hemiacetals with toluenesulfonylhydrazide yields a range of glycosylsulfonohydrazide donors which can be oxidized using cupric chloride in the presence of phosphoric acid and the coordinating additive 2-methyl-2-oxazoline to give useful yields of the fully deprotected glycosyl 1-phosphates.

Stability studies of hydrazide and hydroxylamine-based glycoconjugates in aqueous solution

Glycoconjugates can be readily formed by the condensation of a free-reducing terminus and a strong α-effect nucleophile, such as a hydrazide or a hydroxylamine. Further characterization of a series of glycoconjugates formed from xylose, glucose and N-acet

Protecting group free glycosidations using p-toluenesulfonohydrazide donors

(Figure Presented) N-Glycopyranosylsulfonohydrazides are introduced as glycosyl donors for protecting group free synthesis of O-glycosides, glycosyl azides, and oxazolines. Mono- and disaccharides containing a reducing terminal N-acelylglucosamine residue were condensed with p-toluenesulfonylhydrazide to give the desired β-D-pyranose donors. These donors can be activated with NBS and then glycosidated with the desired alcohol or transformed to the oxazoline or glycosyl azide.
