Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. The appropriate choice can avoid electrode passivation, which strongly inhibit the efficient activation of substrates. 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11. In a Article，once mentioned of 499-40-1, Application of 499-40-1

Halogenido and carboxylato Ru(II) half-sandwich complexes of the general composition [Ru(eta6-p-cym)(dpa)X]PF6 (1-5) were prepared and thoroughly characterized with various techniques (e.g., mass spectrometry, NMR spectroscopy and X-ray analysis); dpa = 2,2?-dipyridylamine; p-cym = p-cymene; X = Cl- (for 1), Br- (for 2), I- (for 3), valproate(1-) (for 4) or 4-phenylbutyrate(1-) (for 5). A single-crystal X-ray analysis showed a pseudo-octahedral piano-stool geometry of [Ru(eta6-p-cym)(dpa)I]PF6 (3), with a eta6-coordinated p-cymene, bidentate N-donor dpa ligand and iodido ligand coordinated to the Ru(II) atom. The results of the 1H-NMR solution behaviour studies proved that the complexes 1-5 hydrolyse were in the mixture of solvents used (10% MeOD-d4/90% D2O). Complexes 1-5 were in vitro inactive against the A2780 human ovarian carcinoma cell line, up to the highest tested concentration (IC50 > 100 muM).

Reaction of (-) 2-tert-butyl-2-methyl-1,3-benzodioxole-4-carboxylic acid with per-O-acetyl-D- and L-glucopyranosyl bromides yielded diastereomeric per-O-acetylated glycopyranosyl 2-tert-butyl-2-methyl-1,3-benzodiazole-4-carboxylates. Their 1H-n.m.r. signals, especially the strong singlet peaks of tert-Bu and Me groups in the 1-ester portion were diagnostic for the determination of the D,L-configuration and optical purity of monosaccharides.

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

A series of C3 O-functionalized 2-acetamido-2-deoxy-4-beta-d- glucuronides were synthesized to explore noncharge interactions in subsite 2 of the influenza virus sialidase active site. In complex with A/N8 sialidase, the parent compound (C3 OH) inverts its solution conformation to bind with all substituents well positioned in the active site. The parent compound inhibits influenza virus sialidase at a sub-muM level; the introduction of small alkyl substituents or an acetyl group at C3 is also tolerated.

The synthesis of a series of six-membered 2-acetamido l-iminosugar C-alkyl and C-aryl glycosides is reported. A diastereoselective sugar-ring enlargement/C-alkylation (or arylation) /ring-contraction sequence applied to d-gluco- and d-manno-configured 2-acetamido azidolactols provides new l-iminosugar C-glycosides. The 1,2-trans stereocontrolled introduction of the pseudoanomeric substituent in these heterocycles strongly suggests a NHAc neighbouring-group participation. In their deprotected form, the nine iminosugars exhibit moderate hexosaminidases and beta-glucuronidase inhibition.
