Through the synergistic catalytic effect of the halogen bond (XB) donor and thiourea catalyst, a direct alpha-selective N-glycosylation of the amide residue of asparagine derivative was achieved using readily accessible glycosyl trichloroacetimidate. n-Butyl methyl ether was found to be the most suitable solvent for the alpha-selectivity.

In a document type is Article, introducing its new discovery.

Obtaining high stereoselectivity in glycosylation reactions is often challenging in the absence of neighboring group participation. In this study, we demonstrate that activation of glycosyl trichloroacetimidate donors with immobilized perchloric acid on silica (HClO4-SiO2) provides higher alpha-selectivity than trimethylsilyl triflate (TMSOTf) for reactions that do not involve neighboring group participation.

[2-13C]-Quercetin-4′-O-beta-glucoside was synthesised in four steps and 28% yield from barium [13C]-carbonate. This short route will be applicable to the synthesis of radiolabelled quercetin-4′-O-beta-D-glucoside from barium [14C]-carbonate. The most important feature is control of the regiochemistry and stereochemistry of glycosylation before introduction of the isotopic label. The synthesis also uses only benzyl protecting groups allowing global deprotection in the last step. (C) 2000 Elsevier Science Ltd.

(Chemical Equation Presented) The development of a new method for stereoselective glycosylation with glycosyl trichloroacetimidate donors employing cationic palladium(II), Pd(CH3CN)4(BF 4)2, is described. This process employs Pd(CH 3CN)4(BF4)2 as an efficient activator, providing access to a variety of disaccharides and glycopeptides. This reaction is highly stereoselective and proceeds under mild conditions with low catalyst loading. Interestingly, this palladium catalysis directs beta-glucosylations in the absence of classical neighboring group participation.

Tetra-O-benzylglucose 1 and trichloroacetonitrile afford in a base catalyzed, fast, and reversible reaction the beta-O-glycosyl imidate 3-beta, which is transformed slowly into the alpha-isomer 3-alpha.Both results, the reactivity differences of 2alpha,beta and the stability differences of 3-alpha/beta are due to lone pair repulsions implicated in the anomeric effect.

The O-benzylated alpha- and beta-glucosyl trichloroacetimidates 1a-alpha and 1a-beta afforded with the phosphinic acid derivative 2 and the phosphonic acid derivative 3 directly the corresponding O-glucosylated products 4 and 5, resp., with inversion at the anomeric center.The corresponding O-acetylated trichloroacetimidates 1b-alpha and 1b-beta provided both the beta-products due to neighboring group participation.With the amidophosphoric acid derivative 6 and the trichloroacetimidate 1b-alpha the O-glucosylated compound 8-beta was obtained.The O-acetylated 6-deoxy-L-talopyranosyl donor 12 behaved similarly.With compound 2 the alpha-phosphinate 13 was formed.Dibenzyl phosphate gave the alpha-phosphate 14; subsequent debenzylation led to the 6-deoxy-alpha-L-talopyranosyl phosphate 15.

A novel and efficient glycosyl donor having a p- trifluoromethylbenzylthio-N-p-trifluoromethylphenylformimidate group at an anomeric position is easily prepared by the addition of anomeric hydroxy group of 2,3,4,6-tetra-O-benzyl-alpha,beta-D-glucopyranose to p-trifluoromethylphenyl isothiocyanate, followed by treatment with p-trifluoromethylbenzyl bromide. Catalytic and stereoselective glycosylation of various glycosyl acceptors with the above glycosyl donor smoothly proceeds by using various protic and Lewis acid catalysts which interact with its nitrogen atom. Further, catalytic and highly 1,2-cis or 1,2-trans stereoselective and chemoselective glycosylation between two different “armed” and “disarmed” glycosyl p- trifluoromethylbenzylthio-N-p-trifluoromethylphenylformimidates is also performed effectively in the presence of a catalytic amount of trifluoromethanesulfonic acid (TfOH) at -78 C in tBuOMe or EtCN, respectively. These glycosylations are applied to successful one-pot sequential syntheses of trisaccharides.

In the aim of developing new procedures for efficient oligosaccharide assembly, a range of 5-thiazolinyl (STaz) glycosides have been synthesized. These novel derivatives were evaluated against a variety of reaction conditions and were shown to be capable of being chemoselectively activated in the armed-disarmed fashion. More over, the S-thiazolinyl moiety exhibited a remarkable propensity for selective activation over other common leaving groups. Conversely, a variety of leaving groups could be selectively activated over the STaz moiety, which, in turn, allowed STaz/S-ethyl and STaz/S-phenyl orthogonal approaches. To demonstrate versatility of novel STaz derivatives, a number of oligosaccharide targets have been synthesized in a convergent selective, orthogonal, and chemoselective fashion.

Photoinduced glycosylation of alcohols with alpha-glucosyl trichloroacetimidates, using aryl urea and thioureas as organo photoacids, was examined under long wavelength UV (ultraviolet) irradiation. The results show, for the first time, that such glycosylations proceed effectively to give the corresponding glycosides in high yields. In addition, high beta-stereoselectivity was obtained under high concentration conditions, whereas high alpha-stereoselectivity was realized under low concentration conditions.

Preparation of three positional isomers of diglucosyl-cyclomaltohexaose

Three positional isomers of diglucosyl-cyclomaltohexaose (diglucosyl-cG6) were chemically synthesized via 61,62-, 61,63-, and 61,64-di-O-(tert-butyldimethylsilyl)-cG6s (1, 2, and 3) prepared regiospecifically. Glucosylation of bis(2,3-di-O-acetyl)tetrakis(2,3,6-tri-O-acetyl)-cG6s obtained from the three regioisomeric compounds 1, 2, and 3 with 2,3,4,6-tetra-O-benzyl-1-O-trichloroacetimidoyl-alpha-D-glucopyranose, followed by debenzylation and then deacetylation, afforded 61,62-, 61,63-, and 61,64-di-O-(alpha-D-glucopyranosyl)-cG6s (10, 11, and 12) together with configurational isomers. The desired compounds 10, 11, and 12 containing two (1 ? 6)-alpha-linkages were isolated from the mixtures of their configurational isomers by high performance liquid chromatography. The three diglucosyl-cG6s synthesized chemically were used as authentic samples to identify the components in a mixture of diglucosyl-cG6s produced by an enzymatic process.
