Abstract
A DMF-modulated glycosylation approach for the stereoselective synthesis of α-Kdo glycosides with readily accessible peracetylated Kdo ynenoate as a donor was described. By utilizing this approach, we completed the synthesis of various linkage types of Kdo-Kdo disaccharides and the α-Kdo-containing protected trisaccharide variant relevant to the lipopolysaccharide of Coxiella burnetii strain Nine Mile.

Stereocontrolled Synthesis of α-3-Deoxy-d-manno-oct-2-ulosonic Acid (α-Kdo) Glycosides Using C3-p-Tolylthio-Substituted Kdo Donors: Access to Highly Branched Kdo Oligosaccharides. Angew Chem Int Ed Engl 2024; 63:e202313985.

Abstract
3-Deoxy-d-manno-oct-2-ulosonic acid (Kdo) is an eight-carbon monosaccharide found widely in bacterial lipopolysaccharides (LPSs) and capsule polysaccharides (CPSs). We developed an indirect method for the stereoselective synthesis of α-Kdo glycosides with a C3-p-tolylthio-substituted Kdo phosphite donor. The presence of the p-tolylthio group enhanced the reactivity, suppressed the formation of elimination by-products (2,3-enes), and provided complete α-stereocontrol. A variety of Kdo α-glycosides were synthesized by our method in excellent yields (up to 98 %). After glycosylation, the p-tolylthio group can be efficiently removed by free-radical reduction. Subsequently, the orthogonality of the phosphite donor and thioglycoside donor was demonstrated by the one-pot synthesis of a trisaccharide in Helicobacter pylori and Neisseria meningitidis LPS. Moreover, an efficient total synthesis route to the challenging 4,5-branched Kdo trisaccharide in LPSs from several A. baumannii strains was highlighted. To demonstrate the high reactivity of our approach further, the highly crowded 4,5,7,8-branched Kdo pentasaccharide was synthesized as a model molecule for the first time. Additionally, the reaction mechanism was investigated by DFT calculations.

Abstract
Disaccharide units containing a latent aldehyde surrogate at O4 provide late-stage access to terminal aldehyde LMWH and HS deca and dodecasaccharides.
d-Glucosamine derivatives bearing latent O4 functionality provide modified H/HS-type disaccharide donors for a final stage capping approach enabling introduction of conjugation-suitable, non-reducing terminal functionality to biologically important glycosaminoglycan oligosaccharides. Application to the synthesis of the first O4-terminus modified synthetic LMWH decasaccharide and an HS-like dodecasaccharide is reported.

Abstract
To develop a convenient method for the preparation of an alpha-Kdo derivative carrying a functional spacer at the reducing end, we examined anomeric O-acylation using Kdo and halogenated alkyl/aryl isocyanates as nucleophile and electrophiles, respectively. Reaction of a Kdo derivative with 2-chloroethyl isocyanate in the presence of DMAP gave an alpha-spiro product (82%) and an alpha-Kdo derivative of a dimeric isocyanate adduct (10%). Similar reaction with 4-(chloromethyl)phenyl isocyanate gave only the corresponding alpha-spiro product (81%). The NMR data show that the pyranose rings of both the alkyl and aryl spiro products adopt the 5C2 conformation. Thus, we accomplished alpha-selective anomeric O-acylation by coupling the Kdo derivative with alkyl and aryl isocyanates.

Abstract
The reaction of tert-butyl (4,5,7, 8-tetra-O-acetyl-3-deoxy-alpha-D-manno-2-octulopyranosyl chloride)onate donor 7 with the 6-formylgalactopyranoside acceptor 4 in the presence of SmI(2) provided only the KDO alpha-C-disaccharide 8. The bulky tert-butyl ester in the donor was used to reverse the stereochemical outcome of C-glycosylation, stereoselectively forming the alpha-"C"-disaccharide of KDO.

Abstract
3,7-Anhydro-D-glycero-D-ido-octitol 1,5,6-trisphosphate (5) was designed as a novel IP(3)-receptor ligand having a C-glycosidic structure and was synthesized via a radical cyclization reaction with a temporary connecting vinylsilyl tether as the key step. The phenyl 2-O-dimethylvinylsilyl-3,4, 6-tri-O-benzyl-1-seleno-beta-D-glucopyranoside (7), in the usual (4)C(1)-conformation, was successively treated with Bu(3)SnH/AIBN and under Tamao oxidation conditions to give a mixture of five C-glycosidic products. On the other hand, similar successive treatment of the corresponding 3,4-di-O-TBS-protected substrates 13 and 24, which were in an unusual (1)C(4)-conformaion due to the steric repulsion between the bulky silyl protecting groups, gave the desired 1alpha-C-glycosides 18 and 25, respectively, as the major products. Thus, the course of the radical cyclization was effectively controlled by a change in the conformation of the pyranose ring into a (1)C(4)-form due to steric repulsion between the adjacent bulky TBS-protecting groups at the 3- and 4-hydroxyl groups. From 25, the target 5 was synthesized via phosphorylation of the hydroxyls by the phosphoramidite method. The C-glycoside trisphosphate 5 has significant binding affinity for IP(3) receptor of calf cerebella.

Abstract
The synthesis of the lipopolysaccharide fragment O-(4,5,7,8-tetra-O-acetyl-3-deoxy-N-methyl-alpha-D-manno-2- octulopyranosylonamide)-(2-->6)-O-(2-deoxy-2-[(3R)-3- dodecanoyloxytetradecanamido]-4-O- phosphono-3-O-tetradecanoyl-beta-D-glucopyranosyl)-(1-->6)-1-O-acetyl-2- deoxy-2 - [(3R)-3-dodecanoyloxytetradecanamido]-3-O-tetradecanoyl-alpha-D- glucopyranose (35 alpha) is performed via anomeric O-alkylation. With this objective, the 2-azido-3-O-benzyl-2-deoxy-6-O-trifluoromethanesulfonyl-beta-D-glu copyranosides 5, 7, and 19 alpha, beta were synthesized from D-glucal and employed as alkylating agents. Reaction of 5 with the O-cyclohexylidene-protected Kdo-derivative 10 afforded the desired alpha-linked disaccharide, tert-butyldimethylsilyl 4-O-allyl-2-azido-3-O-benzyl-2-deoxy-6- O-(4,5:7,8-di-O-cyclohexylidene-3-deoxy-N-methyl-alpha-D-manno-2- octulopyranosylonamide)-beta-D-glucopyranoside (11); even better yields of the structurally related disaccharide 12 were obtained with the 4-O-unprotected 7 as alkylating agent. 1-O-Desilylation of 12 furnished the lactol 20, which could be alkylated at the anomeric position with 1-O-allyl protected alkylating agents 19 alpha and 19 beta, both of which furnished exclusively the desired beta-(1-->6)-linked trisaccharides allyl O-(4,5:7,8-di-O-cyclohexylidene-3- deoxy-N-methyl-alpha-D-manno-2-octulopyranosylonamide)-(2-->6)-O-( 2-azido-3- O-benzyl-2-deoxy-beta-D-glucopyranosyl)-(1-->6)-2-azido-3, 4-di-O-benzyl-2-deoxy-alpha- (21 alpha) and -beta-D-glucopyranoside (21 beta), respectively. Phosphorylation with diphenyl phosphorochloridate, replacement of the O-cyclohexylidene protective group by O-triethylsilyl (TES) protective groups, removal of the 1-O-allyl group, azido group reduction, subsequent N-acylation, and then O-acetylation provided the key 1-O-acetyl protected intermediate 30 alpha. Removal of the O-TES groups, subsequent O-acetylation, and hydrogenolytic O-debenzylation furnished O-[4,5:7,8-tetra-O-acetyl-3-deoxy-N-methyl-alpha-D-manno-2- octulopyranosylonamide]-(2-->6)-O-(2-deoxy-4-O-diphenoxyphospho ryl-2-[(3R)- 3-dodecanoyloxytetradecanamido]-beta-D-glucopyranosyl)-(1-->6)-1-O -acetyl-2- deoxy-2[(3R)-dodecanoyloxytetradecanamido]-alpha-D-glucopyranose (33 alpha), which underwent the required selective O-tetradecanoylation at the 3-O- and 3'-O-position, thus furnishing, after hydrogenolytic O-dephenylation of the diphenoxyphosphoryl group, the target molecule 35 alpha.
