Carbon tetrachloride-free allylic halogenation-mediated glycosylations of allyl glycosides
Das, Anupama,Jayaraman, Narayanaswamy
, p. 9318 - 9325 (2021/11/13)
The allylic bromination of allyl glycosides is conducted using NBS/AIBN reagents in (EtO)2CO and PhCF3 solutions, without using CCl4 as a solvent. The activated mixed halo-allyl glycosides led to glycosylations, mediated by a triflate, in a latent-active
GLUCOSE-RESPONSIVE INSULIN CONJUGATES
-
Page/Page column 119; 141, (2021/02/05)
Glucose-responsive insulin conjugates that contain one or more trisaccharides are provided. Such insulin conjugates may display a pharmacokinetic (PK) and/or pharmacodynamic (PD) profile that is responsive to the systemic concentrations of a saccharide such as glucose or alpha-methylmannose, even when administered to a subject in need thereof in the absence of an exogenous multivalent saccharide-binding molecule.

Pentopyranoside and 6-deoxyhexopyranosides, such as those from D-xylose, L-arabinose and L-fucose are components of natural products, oligosaccharides or polysaccharides. Lewis acid promoted anomerisation of some of their alkyl O- and S-glycopyranosides i
Glycosylation with 3,5-Dimethyl-4-(2′-phenylethynylphenyl)phenyl (EPP) Glycosides via a Dearomative Activation Mechanism
Hu, Zhifei,Tang, Yu,Yu, Biao
supporting information, p. 4806 - 4810 (2019/03/26)
A highly effective and versatile glycosylation method is developed, which uses 3,5-dimethyl-4-(2′-phenylethynylphenyl)phenyl (EPP) glycosides as donors and NIS/TMSOTf as promoter and proceeds via an unprecedented dearomative activation mechanism.

-
Paragraph 0041; 0046, (2017/04/28)
The invention discloses epiandrosterone glycosylation derivatives and dehydrogenated epiandrosterone glycosylation derivatives, and a preparation method thereof. The preparation method comprises the following steps: respectively carrying out coupling reac
3-(Dimethylamino)-1-propylamine: A cheap and versatile reagent for removal of byproducts in carbohydrate chemistry
Andersen, Sofie Meng,Heuckendorff, Mads,Jensen, Henrik H.
supporting information, p. 944 - 947 (2015/04/14)
Inexpensive 3-(dimethylamino)-1-propylamine (DMAPA) was found to be effective in anomeric deacylation reactions giving 1-O deprotected sugars in high yield as precursors for the formation of imidate glycosyl donors. DMAPA was also found to be useful for removing excess reagents such as benzoyl chloride, tosyl chloride, and 2,2,2-trifluoro-N-phenylacetimidoyl chloride. The deacylation reaction could be conducted in moist THF and did not require chromatographic purification since an acidic wash was sufficient to remove excess reagent and the formed byproduct.
2′-Deoxy-2′,2′-difluorothymidine analogues for radiolabeling with fluorine-18 and other biomedical applications
Doepner, Andreas M.,Aboagye, Eric O.,Barrett, Anthony G.M.
, p. 3293 - 3297 (2015/03/04)
Novel 2′-deoxy-2′,2′-difluorothymidine analogues with potential applications as antiviral, cytotoxic and cancer imaging agents have been synthesized. Introduction of the hydroxymethyl functionality at the 5-position of 2′-deoxy-2′,2′-difluoruridine provided a key intermediate with a suitable synthetic handle for the generation of these nucleoside derivatives.

Cross metathesis assisted solid-phase synthesis of glycopeptoids
Khan, Sharaf Nawaz,Kim, Arim,Grubbs, Robert H.,Kwon, Yong-Uk
, p. 2952 - 2955 (2012/07/30)
A solid-phase synthesis of glycopeptoids was explored through olefin cross metathesis (CM). Peptoids and sugar derivatives with appropriate olefin moieties were coupled in the presence of an olefin metathesis catalyst to afford glycopeptoids in good yield
