Pal, Kumar Bhaskar; Lee, Jiande; Das, Mrinmoy; Liu, Xue-Wei published an article in 2020, the title of the article was Palladium(II)-catalyzed stereoselective synthesis of C-glycosides from glycals with diaryliodonium salts.SDS of cas: 2873-29-2 And the article contains the following content:

An efficient palladium(II)-mediated C-glycosylation of glycals with diaryliodonium salts is described, providing a new strategy for the synthesis of 2,3-dideoxy C-aryl glycosides with excellent stereoselectivity. The C-glycosylation of a diverse range of glycals, including D-glucal, D-galactal, D-allal, L-rhamnal, L-fucal, L-arabinal, D-maltal, and D-lactal, occurred effectively and the corresponding C-glycosides were obtained in moderate to good yields. This protocol is commended as a significant addition to the field of carbohydrate chem. due to the rich functional group compatibility, broad range of substrate scope and exceptional α-stereoselectivity. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).SDS of cas: 2873-29-2

And the article contained the following:

Regio- and 1,2-cis-α-stereoselective glycosylations were investigated using 1,2-anhydroglucose donors and trans-1,2-diol sugar acceptors in the presence of a diboron catalyst. The reactions proceeded smoothly to provide the corresponding 1,2-cis-α-glycosides with consistently very high stereoselectivity and were regioselectivity controlled by the protecting groups of the acceptor. The present glycosylation method was applied successfully to the efficient synthesis of α-1,3-glucan pentasaccharide. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Related Products of 2873-29-2

Bi(OTf)3 promoted direct and highly stereoselective glycosylation of “disarmed” and “armed” glycals to synthesize 2-deoxyglycosides has been reported. The tunable and solvent-controlled chemoselective activation of deactivated glycal donors distinguishing the competitive Ferrier and 1,2-addition pathways was discovered to improve substrate scope. The practical versatility of the method has been amply demonstrated with the oligosaccharide syntheses and 2-deoxyglycosylation of high-value natural products and drugs.

On January 6, 2020, Nawoj, Miroslaw; Grobelny, Artur; Mlynarski, Jacek published an article.Computed Properties of 2873-29-2 The title of the article was Macrolide Core Synthesis of Calysolin IX Using an Intramolecular Glycosylation Approach. And the article contained the following:

The utility of intramol. glycosylation for the synthesis of the 27-membered macrocyclic ring is highlighted in this first total synthesis of the most complex resin glycoside isolated to date – Calysolin IX. Oligosaccharide-containing macrolides core was effectively constructed by TfOH/NIS-promoted intramol. glycosylation of thioglycosyl donor. As the glycosidic bond must be created en route to target structure, we show that this unusual yet efficient approach can effectively reduce the number of steps in the total synthesis of complex natural macrolides. This attempt is documented as an efficient tool in the synthesis of gigantic macrolide rings thus proving their practical utility in the total synthesis of sugar-containing targets. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Computed Properties of 2873-29-2

Carmen published an article.Electric Literature of 2873-29-2 The title of the article was Copper Reactivity Can Be Tuned to Catalyze the Stereoselective Synthesis of 2-Deoxyglycosides from Glycals. And the article contained the following:

We demonstrate that tuning the reactivity of Cu by the choice of oxidation state and counterion leads to the activation of both “armed” and “disarmed” type glycals toward direct glycosylation leading to the α-stereoselective synthesis of deoxy-glycosides in good to excellent yields. Mechanistic studies show that CuI is essential for effective catalysis and stereocontrol and that the reaction proceeds through dual activation of both the enol ether as well as the OH nucleophile.

And the article contained the following:

C-Glycosides are metabolically stable mimics of natural O-glycosides and are expected to be useful tools for investigation of the biol. functions of glycans. Here, we describe the synthesis of a series of aryl and vinyl C-glycosides by stereoinvertive sp3-sp2 cross-coupling reactions of 2-deoxyglycosyl boronic acid derivatives with aryl or vinyl halide, mediated by a photoredox/nickel dual catalytic system. Hydrogenation of the vinyl C-glycosides afforded C-linked 2′-deoxydisaccharide analogs.

And the article contained the following:

Direct and practical anomeric O-arylation of sugar lactols with substituted arylboronic acids has been established. Using copper catalysis at room temperature under an air atm., the protocol proved to be general, and a variety of aryl O-glycosides have been prepared in good to excellent yields. Furthermore, this approach was extended successfully to unprotected carbohydrates, including α-mannose, and it was demonstrated here how the interaction between carbohydrates and boronic acids can be combined with copper catalysis to achieve selective anomeric O-arylation.
