Abstract
Metabolic glycan labeling (MGL) has gained wide utility and has become a useful tool for probing glycosylation in living systems. For the past three decades, the development and application of MGL have mostly focused on animal glycosylation. Recently, exploiting MGL for studying plant glycosylation has gained interest. Here, we describe a systematic evaluation of MGL for fluorescence imaging of root glycans in Arabidopsis thaliana. Nineteen monosaccharide analogues containing a bioorthogonal group (azide, alkyne, or cyclopropene) were synthesized and evaluated for metabolic incorporation into root glycans. Among these unnatural sugars, 14 (including three new compounds) were evaluated in plants for the first time. Our results showed that five unnatural sugars metabolically labeled root glycans efficiently, and enabled fluorescence imaging by bioorthogonal conjugation with fluorophores. We optimized the experimental procedures for MGL in Arabidopsis. Finally, distinct distribution patterns of the newly synthesized glycans were observed along the root developmental zones, thus indicating regulated biosynthesis of glycans during root development. We envision that MGL will find broad applications in plant glycobiology.

Abstract
Starting from 1,2,4-tri-O-acetyl-3,6-anhydro-alpha-d-galactopyranose, 4-O-acetyl-3,6-anhydro-1,2-O-(1-cyanoethylidene)-alpha-d-galactopyranose (7) was synthesized by treatment with cyanotrimethylsilane. Additionally, 3,4-di-O-acetyl-1,2-O-(1-cyanoethylidene)-6-O-tosyl-alpha-d-galactopyranose was prepared from the corresponding bromide and both cyanoethylidene derivatives were used as donors in glycosylation reactions. The coupling with benzyl 2,4,6-tri-O-acetyl-3-O-trityl-beta-d-galactopyranoside provided exclusively the beta-linked disaccharides in approximately 30% yield. The more reactive methyl 2,3-O-isopropylidene-4-O-trityl-alpha-l-rhamnopyranoside gave with donors 3 and 7 the corresponding disaccharides in nearly 60% yield. Furthermore, the synthesis of 3,6-anhydro-4-O-trityl-1,2-O-[1-(endo-cyano)ethylidene]-alpha-d-galactopyranose, which can be used as a monomer for polycondensation reaction is described.

FEBS Lett 2006; 580:3905-10.

Abstract
Mutagenesis of Asp-196 into Ala yielded an inactive variant of Leuconostoc mesenteroides sucrose phosphorylase (D196A). External azide partly complemented the catalytic defect in D196A with a second-order rate constant of 0.031 M-1 s-1 (pH 5, 30 degrees C) while formate, acetate and halides could not restore activity. The mutant utilized azide to convert alpha-D-glucose 1-phosphate into beta-D-glucose 1-azide, reflecting a change in stereochemical course of glucosyl transfer from alpha-retaining in wild-type to inverting in D196A. Phosphorolysis of beta-D-glucose 1-azide by D196A occurred through a ternary complex kinetic mechanism, in marked contrast to the wild-type whose reactions feature a common glucosyl enzyme intermediate and Ping-Pong kinetics. Therefore, Asp-196 is identified unambiguously as the catalytic nucleophile of sucrose phosphorylase, and its substitution by Ala forces the reaction to proceed via single nucleophilic displacement. D196A is not detectably active as alpha-glucosynthase.

Abstract
1-Deoxynojirimycin, 1-deoxymannojirimycin, and 1-deoxygalactostatin have been synthesized by epoxidation of tri-O-acetyl-6-deoxyhex-5-enopyranosyl azides followed by methanolysis, deacetylation, and catalytic hydrogenation. 1,6-Dideoxygalactostatin was obtained by the reaction of 2,3,4-tri-O-acetyl-6-deoxy-beta-L-arabino-hex-5-enopyranosyl azide with NIS in methanol followed by deacetylation and catalytic hydrogenation. The overall yields were 4.4-23.5% over seven to nine steps.

Abstract
A number of beta-d-glycosyl azide derivatives undergo reduction on treatment with tetrathiomolybdate to produce the corresponding beta-d-glycosylamines exclusively without anomerization under very mild and neutral reaction conditions. Acetyl, allyl, benzoyl, and benzyl protective groups are left untouched under the reaction conditions. An exclusive selectivity in the reduction of anomeric azides is observed, while the C-2 and C-6 azides are left untouched.

Abstract
Reaction of glycosyl trimethylphosphinimides with carbon disulfide under mild conditions (room temperature, short reaction time) leads to symmetrical glycosyl carbodiimides. Addition of bis(trimethylsilyl)carbodiimide to peracetylated aldoses under the influence of SnCl(4) afforded N,N-bis(glycosyl)cyanamides for the first time. Readily accessible unsymmetrical N,N'-bis(glycosyl)thioureas can be desulfurated and transformed into the corresponding carbodiimides using HgO in CHCl(3)/water at room temperature.

Abstract
The first total synthesis of one of the spicamycin congeners, SPM VIII (3), is described. A preliminary model study for construction of the characteristic N-glycoside linkage in spicamycin using tetra-O-benzyl-beta-D-mannopyranosylamine (13) and halopurines 5 revealed that Pd-catalyzed conditions successfully provided the coupling products 14 and 15 in good yields. It was also shown that thermal anomerization of the N-glycosides easily occurred, which resulted in the predominant formation of the beta-anomer as the thermodynamically favored compound, and the activation energy of anomerization of 15 was estimated to be ca. 30 kcal/mol. The novel aminoheptose unit of spicamycin 6 was prepared stereoselectively by carbon elongation of an acyclic aldehyde, prepared by ring cleavage reaction of a highly functionalized cyclohexane derived from naturally abundant myo-inositol. The Pd-catalyzed coupling reaction of the beta-heptopyranosylamine 6 with protected 6-chloropurine 5d, followed by deprotection, provided spicamycin amino nucleoside 2, whose condensation with dodecanoylglycine completed the total synthesis of 3. This study confirmed the proposed unique structure of a novel nucleoside antibiotic.

Abstract
Protected glycosyl azides react with acyl chlorides in the presence of triphenylphosphine to afford glycosylamides in high yields, at room temperature. Starting from the beta-glycosyl azides, the reaction is highly stereoselective and occurs with retention of configuration, whereas the alpha-azido anomers display a lower stereoselectivity giving rise to alpha/beta mixtures of glycosylamides. The reaction was applied to several monosaccharidic azides and to lactosyl azide with various acyl chlorides; it was shown to be of general use for preparing 1,2-trans beta-glycosylamides.
