Abstract
The motif α-D-GalpNAc-(1-3)-D-GalpNAc is very common in Nature and hence its synthesis highly relevant. The synthesis of its azido precursor has been studied and optimized in terms of steps, yields and selectivity. It has been found that glycosylation of the 3,4-diol acceptor is an advantage over the use of a 4-O-protected acceptor and that both regio- and anomeric selectivity is enhanced by bulky 6-O-protective groups. The acceptors and donors are made from common building blocks, limiting protective manipulations, and in this context, unavoidable side reactions.

Abstract
Synthesis of beta-D-Gal-(1 --> 3)-beta-D-GalNAc coupled to HOC2H4NHCOC15H30SH is described. This compound was coadsorbed at various proportions with C2H5OC2H4NHCOC15H30SH to form statistically mixed self-assembled monolayers (SAMs) on gold in an attempt to mimic the properties of the active domain in antifreeze glycoproteins (AFGPs). The monolayers were characterized by null ellipsometry, contact angle goniometry, X-ray photoelectron spectroscopy, and infrared reflection-absorption spectroscopy. The disaccharide compound adsorbed preferentially, and SAMs prepared at a solution molar ratio >0.3 displayed total wetting. The mixed SAMs showed well-organized alkyl chains up to a disaccharide surface fraction of 0.8. The amount of gauche conformers in the alkyls increased rapidly above this point, and the monolayers became disordered and less densely packed. Furthermore, the generated mixed SAMs were subjected to water vapor at constant relative humidity and the subsequent ice crystallization on a cooled substrate was monitored via an optical microscope. Interestingly, rapid crystallization occurred within a narrow range of temperatures on mixed SAMs with a high disaccharide content, surface fraction >0.3. The reported crystallization temperatures and the ice layer topography were compared with results obtained for a much simpler reference system composed of -OH/-CH3 terminated n-alkanethiols in order to account for changes in topography of the water/ice layer with surface energy. Although preliminary, the obtained results can be useful in the search for the molecular mechanism behind the antifreeze activity of AFGPs.

Abstract
The Pk-trisaccharide, linked to a solid carrier, is a potential agent for neutralization of shiga-like toxin in the gastrointestinal tract. Two approaches to the multigram-scale synthesis of a linkable Pk-trisaccharide derivative were therefore investigated. A four-step chemical synthesis yielded 8-methoxycarbonyloctyl beta-lactoside in 75% yield from lactose. Further conversion of this derivative through either multistep organic synthesis or one-step enzymatic galactosylation with UDP-galactose and recombinant alpha-1,4-galactosyltransferase gave the Pk-trisaccharide derivative 8-methoxycarbonyloctyl alpha-D-galactopyranosyl-(1-->4)-beta-D-galactopyranosyl-(1-->4)-beta-D-glucopyranoside in 25% and 68% overall yields from commercial lactose, respectively.

Abstract
Lactose was readily transformed into thexyldimethylsilyl (3,4-O-isopropylidene-beta-D-galactopyranosyl)-(1-->4)-beta- D-glucopyranoside (5); this compound served as intermediate for the generation of partially O-protected lactose building blocks required in oligosaccharide and glycoconjugate synthesis. Thus, from 5 via per-O-benzoylation, desilylation, trichloroacetimidate formation, glycosylation of the Lemieux spacer, and acid-catalyzed de-O-isopropylidenation methoxycarbonyloctyl (2,6-di-O-benzoyl-beta-D-galactopyranosyl)- (1-->4)-2,3,6-tri-O-benzoyl-beta-D-glucopyranoside (12) was obtained. Regioselective benzoylation of 5 with benzoyl cyanide under various conditions afforded 3-O- (13), 2,3,2'-O- (14), 3,2'-O- (16), and 2,2'-O-unprotected (17) lactoside, respectively. De-O-isopropylidenation of 16 gave thexyldimethylsilyl (6-O-benzoyl-beta-D-galactopyranosyl)-(1-->4)-2, 6-di-O-benzoyl-beta-D-glucopyranoside (18), an important 2',3',4'-O-unprotected lactose derivative. Fucosylation of 13 and then de-O-isopropylidenation afforded thexyldimethylsilyl 2,6-di-O-benzoyl-beta-D-galactopyranosyl)-(1-->4)-[(3,4-di-O-acetyl-2-O- benzoyl-alpha-L-fucopyranosyl)-(1-->3)]-2,6-di-O-benzoyl-beta-D- glucopyranoside (21), an important fucosyllactose building block.

Abstract
To contribute to the possibility of studying in greater detail the biological significance of Sda-containing glycans as occur in Tamm-Horsfall glycoprotein, the following three spacer-linked tetrasaccharides have been synthesized: the Sda determinant alpha-Neu p5Ac-(2-->3)-[beta- D-GalpNAc-(1-->4)]-beta-D-Galp-(1-->4)-beta-D-GlcpNAc-(1-->O)(CH2)5NH 2 (1), the Gal-analogue alpha-Neup5Ac-(2-->3)-[beta-D-Galp-(1-->4)]-beta-D-Galp-(1-->4) -beta-D-GlcpNAc-(1-->O)(CH2)5NH2 (2), and the GlcNAc-analogue alpha-Neup5Ac-(2-->3)-[beta-D-GlcpNAc-(1-->4)]- beta-D-Galp-(1-->4)-beta-D-GlcpNAc-(1-->O)(CH2)5NH2 (3). The general trisaccharide acceptor 5-azidopentyl (methyl 5-acetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy- D-glycero-alpha-D-galactonon-2-ulopyranosylonate)-(2-->3)-(2 ,6-di-O-benzyl- beta-D-galactopyranosyl)-(1-->4)-3,6-di-O- benzyl-2-deoxy-2-phthalimido-beta-D-glucopyranoside was prepared, using methyl (phenyl 5- acetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy-2-thio-D-glycero-D-galacto- non- 2-ulopyranosid)- onate as the sialyl donor. For the syntheses of 1, 2, and 3 the glycosyl donors 3,4,6-tri-O- acetyl-2-deoxy-2-phthalimido-alpha-D-galactopyranosyl bromide, 2,3,4,6-tetra-O-acetyl-alpha-D- galactopyranosyl bromide, and 3,4,6-tri-O-acetyl-2-deoxy-2-phthalimido -beta-D-glucopyranosyl trichloroacetimidate, respectively, proved to be the most suitable.

Abstract
p-Methoxyphenyl (pMP) beta-D-glycopyranosides (Glc, Gal, GlcNPhth, GalNPhth, GlcNTroc, Gal beta 4Glc, Gal alpha 4Gal) were prepared from the corresponding 1-O-acetyl sugars in 79-90% yield, using boron trifluoride etherate as promoter. Treatment of the pMP glycosides with acyl chlorides or bromides in the presence of various Lewis acids gave the corresponding glycosyl chlorides and bromides in 81-98% yield. Treatment of the acyl-protected pMP glycosides with thiophenol and boron trifluoride etherate gave the corresponding thioglycosides in 80-100% yield and high (> 20:1) beta/alpha selectivity. The stability of pMP glycosides was investigated against a series of reagents.

Abstract
3,4,6-Tri-O-benzoyl-2-(benzoyloxyimino)-2-deoxy-alpha-D-arabino-++ +hexopyranosy l bromide (2) reacts with the O-protected 2-deoxy-2-phthalimido-beta-D-galactosamines 3 and 4 in the presence of silver triflate and sym-collidine at -78 degrees C, to give alpha,beta-(1-->1)-linked disaccharides 6a and 7a with an excellent selectivity. The 2-oxyimino function was stereospecifically converted into a 2-acetamido group by use of the LiBH4-Me3SiCl-THF reductive species, furnishing, after acetylation, the alpha-D-GlcNAc-(1-->1)-beta-D-GalNPhth nonsymmetrical, trehalose type disaccharides 13 and 14 related to tunicamycin (1, part A). Similarly, alpha-D-GlcNAc-(1-->1)-beta-D-GlcNPhth (15) was prepared, starting from 2 and 5. The factors governing the stereoselectivity of the glycosylation reactions were determined.

It was synthesized from suitably protected monosaccharide and aromatic precursors. The readily available 4,6-O-benzylidene-1,2-O-(R)-propylidene-alpha-D-glucopyranose was converted in six steps into 2-O-acetyl-4-O-benzoyl-3-O-benzyl-6-deoxy-alpha-D-glucopyranosyl bromide, which was condensed with methyl 3-O-benzyl-2,6-dideoxy-alpha-D-arabino-hexopyranoside in the presence of mercury(II) cyanide. Methyl 4-O-(2-O-acetyl-4-O-benzoyl-3-O-benzyl-6-deoxy-beta- D-glucopyranosyl)-3-O-benzyl-2,6-dideoxy-alpha-D-arabino-hexopyranosi de was converted either into methyl 2,6-dideoxy-4-O-(6-deoxy-beta-D- glucopyranosyl)-alpha-D-arabino-hexopyranoside by removal of the protective groups or into methyl 3-O-benzyl-4-O-(3-O-benzyl-2,6-dideoxy-beta-D-arabino-hexopyranosyl)-2,6 - dideoxy-alpha-D-arabino-hexopyranoside (22) by selective deacetylation, Barton deoxygenation, and Zemplén debenzoylation. Disaccharide 22 was deprotonated with butyllithium and treated with 4-benzyloxy-3,5-dichloro-2-methoxy-6-methylbenzoyl chloride to give the title compound 25 after hydrogenolysis.

Abstract
The solution salts of the 6'-sulfate 12, the 4'-sulfate 15 and the 4',6'-disulfate 17 of benzyl 4-O-(beta-D-galactopyranosyl)-beta-D-glucopyranosiduronate 10 have been synthesized. Methyl [benzyl 2,3-di-O-benzoyl-4-O-(2,3-di-O-benzoyl-beta-D-galactopyranosyl)-beta-D-+ ++glucopyranosid]uronate (9) has been prepared as a key intermediate from benzyl 4',6'-O-benzylidene-beta-D-lactopyranoside (2). Protection of 2 at C-6 with the tert-butyldimethylsilyl group, followed by O-perbenzoylation and disilylation, gave benzyl 2,3-di-O-benzoyl-4-O-(2,3-di-O-benzoyl-4,6-O-benzylidene-beta-D-galac top yranosyl)-beta-D-glucopyranoside (7). Oxidation of the 6-position of 7 proved to be difficult. However, 7 could be converted into the tert-butyl glucuronate 8 using chromium trioxide-pyridine and tert-butanol. Simultaneous hydrolysis of the benzylidene acetal and the tert-butyl ester groups, followed by esterification of the resulting free acid with diazomethane, yielded 9. Compound was directly sulfated with sulfur trioxide-trimethylamine within 12 h to give the 6'-sulfate 11. The 4',6-disulfate 16 was accessible by running the reaction under the same conditions for 14 days. The 4'-sulfate 14 was obtained after protecting the 6'-OH group of 9 with benzoyl cyanide to give the 6'-benzoate 13 followed by sulfation under more vigorous reaction conditions. Deesterification of 9, 11, 14, and 16 was achieved by treatment with aqueous sodium hydroxide in tetrahydrofuran to give 10, 12, 15, and 17, respectively.

Abstract
We have recently reported a highly efficient and stereocontrolled synthesis of globotriaosylceramide (Gb3, 1) in optically pure form. Key to our synthetic strategy was the implementation of the two-stage activation of thioglycosides for formation of the glycosidic bonds and the utilization of (2S, 3S, 4E)-2-azido-3-O-(tert-butyldimethylsilyl)-4-octadecen-1,3-di ol (9) as a sphingosine equivalent. The syntheses of Gb3 (1) and lysoGb3 (2) were achieved by stereocontrolled coupling of 2,3,4,6-tetra-O-benzyl-alpha-D-galactosyl fluoride (15) with phenyl O-(6-O-benzoyl-2,3-di-O-pivaloyl-beta-D-galactopyranosyl)- (1----4)-2,3,6-tri-O-pivaloyl-1-thio-beta-D-glucopyranoside (14) to form the P kappa antigen trisaccharide masked as a phenyl 1-thioglycoside at the reducing end. Thioglycoside 16 was converted into glycosyl fluoride 19, which was coupled to 9 in high yield. The coupled product 20 was converted into the title compounds 1 and 2 in four and three steps, respectively. This article presents the total synthesis of 1 and 2 in full experimental detail.

Abstract
Derivatives of glycosides of D-galactosamine were prepared in order to study further the binding requirement of the Gal/GalNAc receptor in mammalian hepatocytes. These structures included N-propanoyl, N-benzoyl, and N,N-phthaloyl derivatives of 2-hydroxyethyl 2-amino-2-deoxy-beta-D-galactopyranoside, 6-amino-hex-1-yl 2-deoxy-2-(trifluoroacetamido)-beta-D-galactopyranoside, the mono- and di-O-methyl derivatives of allyl 2-acetamido-2-deoxy-beta-D-galactopyranoside, and allyl 2-acetamido-2,4-dideoxy-4-fluoro-alpha-D-galactopyranoside. The inhibition results confirmed some of our previous findings on the involvement of the hydroxyl groups, and provided new information on the involvement of the N-substituent, as well as on the requirement of hydrogen bonding of the 4-hydroxyl group in binding.

Abstract
The synthesis of the trisaccharide methyl glycoside beta-D-GalNAc-(1----4)-beta-D-Gal-(1----4)-beta-D-Glc-OMe, which corresponds to the carbohydrate portion of gangliotriosylceramide (asialo GM2), was accomplished by the reaction of 4-O-acetyl-3,6-di-O-benzoyl-2-deoxy-2-phthalimido-D-galactopyranosyl bromide (18) with a benzylated derivative of methyl 4-O-beta-D-galactopyranosyl-beta-D-glucopyranoside. Comparative studies with a 6'-benzyl ether and a 6'-benzoate revealed that the substituent at O-6' is crucial to the outcome of glycosylations at O-4', the ether derivative being much the more reactive. tert-Butyl 4-O-acetyl-3,6-di-O-benzoyl-2-deoxy-2-phthalimido-D-galactopyranoside, which was readily converted into the corresponding bromide 18, was obtained from the gluco derivative via a single-step, crown ether-assisted epimerization.
