Synthesis and enzyme-catalyzed hydrolysis of a radical-masked glycosylated spin-label reagent

N1-Acetoxy-2,2,6,6-tetramethylpiperidin-4-yl 2,3,4,6-tetra-O-benzyl-alpha- and -beta-d-glucopyranosides (3-alpha, beta) and N1-acetoxy-2,2,5,5-tetramethylpyrrolin-3-oyl 2,3,4,6-tetra-O-benzyl-alpha- and -beta-d-glucopyranosylamines (9-alpha, beta) were synthesized in good yield by Schmidt’s glycosylation method. Their subsequent O-debenzylation was proceeded successfully to give the desired products 1-alpha, and 1-beta in good yield, and 2-alpha in a low yield, without 2-beta by only short-timed hydrogenolysis in the presence of palladium-on-carbon (Pd-C) in a CHCl3-MeOH solvent system that included concentrated HCl. Upon enzyme-catalyzed hydrolysis, only 2-alpha was hydrolyzed by the esterase, while both of 1-alpha and 1-beta were not hydrolyzed by any other enzyme such as lipase. These 2-alpha can likely be used as a new water-soluble radical-masked glycosylated spin-label reagent.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of (2R,3R,4S,5R,6R)-3,4,5-Tris(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-yl 2,2,2-trichloroacetimidate, you can also check out more blogs about74808-09-6

Syntheses and Equilibrations of 6- and 7-Carbomethoxy-trans-2-oxadecalins

Syntheses of the title compounds based on a Robinson annulation scheme utilizing tetrahydropyran-4-one are described.The 6-substituted system is elaborated by using Wittig methodology, while the 7-substituted ester is prepared via regioselective enolate formation.The regioselectivity of the latter is verified by preparation of a 5-isomer by reductive carboxylation of the original annulation product.Base-catalyzed equilibrations indicate a slightly preference for the equatorial position than in the 2-decalyl analogue, with entropy contributing little to theconformational free energies.

Potential HIV protease inhibitors: Preparation of di-N-alkylated 2-, 6-, and 2,6-aminodeoxy-derivatives of D-glucose by direct displacement and by a novel reductive-alkylation procedure

Glucose derivatives carrying branched lipophilic groups at the 2-, 6-, and 2,6-positions were required for biological testing as inhibitors of the protease produced by the human immunodeficiency virus. The synthesis of (N-benzyl-N-ethyl)-2-, 6- and 2,6-diaminodeoxy-D-glucose derivatives is described. The 2-tert-amino group was introduced by a two-step reductive alkylation procedure. The novel tertiary aminosugar, 2,6-di-(N-benzyl-N-ethyl)amino-2,6-dideoxy-D-glucose, was made via direct substitution of the sulphonate group in allyl 2-acetamido-2-deoxy-6-O-tosyl-D-glucopyranoside with N-benzylethylamine.

A tetranuclear manganese carboxylate cluster with bis(2-pyridyl)amine ligation: [Mn4O2(O2CEt)7 (bpya)2](ClO4)

The title complex has been prepared and characterized by X-ray crystallography, magnetochemistry, cyclic voltammetry and 1H NMR spectroscopy. The complex contains a [Mn4(mu3-O)2]8+ core with bridging EtCO2- and chelating bpya groups. The magnetochemical studies indicate an S = 0 ground state as a result of antiferromagnetic exchange interactions between the MnIII ions. The 1H NMR spectra support retention of the solid-state structure on dissolution in MeCN.

Two new poloxometalate-based organic/inorganic hybrid compounds, 4(2,2?-DPA)¡¤pseudo-alpha-H4SiMo12O 40¡¤4DMF¡¤2H2O (1) and 4(2,2?-DPA)¡¤pseudo-alpha-H4SiMo12O 40¡¤2H2O (2), have been synthesized and characterized. The crystals of 1 belong to the space group P-1 with a = 13.068 (3), b = 13.706 (2), c = 13.724 (2) A?, alpha = 89.325 (18), beta = 62.516 (11), gamma = 82.260 (15), V = 2157.3 (7) A?3, Dc = 2.183 g/cm3, Z = 1, R = 0.0979 and the crystals of 2 belong to the space group P-1 with a = 11.4688 (10), b = 12.6435 (11), c = 12.8070 (12) A?, alpha = 110.745 (2), beta = 105.329 (2), gamma = 90.46 4 (2), V = 1664.2 (3) A?3, Dc = 2.539 g/cm3, Z = 1, R = 0.0543. Spectroscopic data support the presence of a sizeable electronic interaction between the electron-rich organics and the inorganic SiMo12O404- anions in 1 as well as in 2, both in the solid state and in solution, provided the hybrid compounds are present in high concentrations. The crystal structure determination reveals the absence of any substantial, direct interaction between the organics and the polyoxoanions both within compounds 1 and 2. Therefore the inherent relationship between molecular and crystal structure and the charge-transfer interaction cannot be given yet, despite that it is found that the charge-transfer strength is somewhat related to the distance between the organics and the polyoxoanions.

Bis(acetato-kappa 2O,O?)(di-2-pyridyl-kappaN-amine)copper(II) dihydrate

The copper(II) ion in the title complex, [Cu(C2H3O2)2-(C10H 9N3)].2H2O, is coordinated unsymmetrically to each of the two bidentate acetate ligands and to the N atoms of the di-2-pyridylamine (dpyam) ligand. The copper(II) ion is surrounded by a distorted square-based arrangement of the two dpyam pyridyl N atoms at distances of 1.974 (2) and 1.995 (2) A, and by two acetate O atoms at distances of 1.965 (1) and 1.967 (1) A. The second O atom from each acetate group is involved in weak coordination in the tetragonal positions, at longer Cu-O distances of 2.482 (2) and 2.690 (2) A, completing the six-coordination. The overall geometry at the copper(II) ion is best described as distorted octahedral with elongated axial bonds.
