HYDROGEN FLUORIDE-CATALYZED FORMATION OF GLYCOSIDES. PREPARATION OF METHYL 2-ACETAMIDO-2-DEOXY-β-D-GLUCO- AND -β-D-GALACTO-PYRANOSIDES, AND OF β-(1->6)-LINKED 2-ACETAMIDO-2-DEOXY-D-GLUCO- AND -D-GALACTO-PYRANOSYL OLIGOSACCHARIDES

Dissolution of 2-acetamido-2-deoxy-D-glucose (1) or -D-galactose (2) in anhydrous hydrogen fluoride, followed by addition of methanol, gave stereospecifically the corresponding methyl β-D-glycopyranosides 7 and 8.When solutions of 1 or 2 in hydrogen fluoride were slowly evaporated, mixtures of exclusively β-D-(1->6)-linked di- to hexa-saccharides containing 2-acetamido-2-deoxy-glucosyl (9) and -galactosyl (10) residues were obtained; these were separated by gel permeation chromatography to give pure products.Compounds 7 and 9 were also obtained when solutions of chitin were treated under appropriate conditions.
IN VIVO ASSEMBLY OF ASGPR BINDING THERAPEUTICS
-
, (2022/02/28)
Compounds are provided that assemble together in vivo to form an ASGPR-binding compound that has an asialoglycoprotein receptor (ASGPR) binding ligand bound to an extracellular protein binding ligand for the selective degradation of the target extracellular protein in vivo to treat disorders mediated by the extracellular protein.

, p. 723 - 730 (2017/04/26)
Dinosylated α-d-glucopyranoside was directly transformed into α-d-altropyranosides via in situ formed N-4-nosyl Hough-Richardson aziridine with nitrogen nucleophiles under mild conditions in fair to excellent yields. The scope of the aziridine ring-opening reaction was substantially broadened contrary to the conventional methods introducing solely the azide anion at high temperatures. If necessary, the N-4-nosyl Hough-Richardson aziridine can be isolated by filtration in a very good yield and high purity.
Sugar derived alkamine catalytic imine reduction method
-
Paragraph 0035; 0036; 0037, (2016/10/07)
The invention discloses a method used for catalytic reduction of imine with saccharide-derivatized amino alcohol. According to the method, imine is taken as a substrate. The method comprises following steps: 1) imine and saccharide-derivatized amino alcohol are dissolved in an organic solvent I, wherein molar ratio of imine to saccharide-derivatized amino alcohol ranges from 100:1-20; 2) trichlorosilane with 1.5 to 5 times equivalent weights is added into a solution obtained via step 1) dropwise, an obtained mixture is stirred and reacted for 12 to 36h at a temperature of -20 to 40 DEG C, and a saturated sodium bicarbonate solution is used for quenching; 3) a material obtained via step 2) is extracted with an organic solvent II, and is subjected to column chromatography isolation so as to obtain amine compounds.
