Abstract: Conjugates of 3,4,6-tri-?-acetyl-N-acetylglucosamine and tetraacetyl glucopyranose with alkyl phosphates were synthesized. The dependence of their antibacterial and antituberculosis activities on the length of the alkyl substituent at the phosphate group was found. The conjugates with a decyl substituent exhibited in vitro the highest antituberculosis activity against Mycobacterium tuberculosis H37Rv (MIC 3?mug/mL) but the weakest effect towards Streptococcus aureus and Bacillus cereus (?MIC 125 mug/mL). Vice versa, the conjugates with a cetyl substituent demonstrated the highest antibacterial activity in vitro towards S. aureus and B. cereus (MIC 16 mug/mL) but showed the lowest antituberculosis activity (MIC 12 mug/mL) among the compounds under study.

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.Recommanded Product: 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, you can also check out more blogs about10343-06-3

Polymer brushes (PBs) have been used as supports for the immobilization of palladium complexes on silicon surfaces. The polymers were grown by surface-initiated atom-transfer radical polymerization (SI-ATRP) and postdecorated with dipyridylamine (dpa) ligands. The pendant dpa units were in turn complexed with [Pd(OAc)2] to afford hybrid catalytic surfaces. A series of catalytic samples of various thicknesses (ca. 20-160 nm) and associated palladium loadings (ca. 10-45 nmol cm-2) were obtained by adjusting the SI-ATRP reaction time and characterized by ellipsometry, X-ray reflectivity, X-ray photoelectron spectroscopy, and inductively coupled plasma mass spectrometry (ICP-MS). ICP-MS revealed a near-linear relationship between thickness of the polymer brush and palladium content, which confirmed the robustness of the preparation and postmodification sequence presented herein, rendering possible the creation of functional architectures with predefined catalytic potential. The activities of the catalytic PBs were determined by systematically exploring a full range of substrate-to-catalyst ratios in a model palladium(0)-catalyzed reaction. Quantitative transformations were observed for loadings down to 0.03 mol % and a maximum turnover number (TON) of around 3500 was established for the system. Comparison of the catalytic performances evidenced a singular influence of the thickness on conversions and TONs. The limited recyclability of the hairy catalysts has been attributed to palladium leaching.

Two extended coordination frameworks of CdII-squarate complexes with the formulas [Cd2(C4O4) 2.5(H2O)4](dpaH)¡¤ 1.5(H2O) (1) and [Cd(C4O4)(dpa)(H2O)] (2) (dpa = 2,2?-dipyridylamine) have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction studies. Structural determination reveals that compound 1 consists of a free monoprotonated 2,2?-dipyridylamine ion (dpaH+) and a two-dimensional (2D) anionic, layered framework, {[Cd2(C4O4) 2.5(H2O)4]-}, which is formed with two anti-prismatic square-boxes as the fundamental building unit through the connection between CdII ions and hybrid mu1,2,3-, mu1,2,3,4-squarates. Each square-box acts as a host for the inclusion of one pyridine ring of dpaH+. Adjacent dpaH+ cations are then self-assembled by the parallel alignment of the other pyridine ring of dpaH+ to complete a 3D network with one-dimensional (1D) channels intercalated by water molecules. Compound 2 contains a distorted octahedral CdII center coordinated by two squarates, two waters and one dpa ligand to form a 1D 2-legged, ladder-like framework by the connection of a [Cd(dpa)(mu2-H2O)]24+ dimeric unit and a mu1,2-squarate. Weak pi-pi stacking interaction and hydrogen bonds of N-H…O, O-H…O and C-H…O among the squarate, water and dpa ligands provide additional intra- and intermolecular interactions on the stabilization of these two polymeric frameworks.

A series of new nickel(II) perchlorate complexes containing an alpha-diimine(enR) and the anion of a beta-dione (1,3-ketoenol or 1,3-ketoester, betaH) was prepared and characterized. The composition and the overall structure of the new chelates depend on ligand concentration, on steric and electronic effects induced by substituents within the ligands and the ability of the perchlorate group to coordinate. The IR and electronic excitation spectra of [Ni(BnR)2beta]ClO4 and [Ni(enR)beta(O2ClO2)] indicate, in conjunction with other physicochemical measurements, bidentate coordination of the ligands and replacement of the (O,O?) perchlorato group by basic solvents. The structure of the new chelates was further supported by an X-ray structure analysis of [Ni(ncup)2Etacet]ClO4, where ncup denotes neocuproine and Etacet the anion of the ethyl acetoacetate (orthorhombic, space group Pc21n, a = 14.087(5), b = 14.713(5) and c= 15.952(5) A, Z = 4). The coordination sphere of nickel is a distorted octahedron, arised from the chromophore NiN4O2, in which the base is favored by three neocuproine nitrogens and one Etacet oxygen. The apical sites are occupied by the remaining oxygen and nitrogen atoms, one from Etacet and one from neocuproine respectively.

We describe the beta-ortho-methoxybenzoate as a shelf stable and practical C-1 nucleofuge for catalytic chemical glycosylation in which the benzoic acid by-product can be easily removed, reisolated, and potentially recycled after the glycosylation reaction. This new type of glycosyl donor can be efficiently activated by a range of promoters, including Bi(OTf)3, Fe(OTf)3, TMSOTf (TMS = trimethylsilyl), and triflic acid, with low (<10 mol-%) catalyst loadings. The donor shows higher reactivity than analogous benzoate, p-methoxybenzoate and p-cyano-o-methoxybenzoate donors. In glycosylation reactions with o-methoxybenzoate donors, the yields of disaccharide products were good to excellent for various glycosyl acceptors, including a carbohydrate-based secondary alcohol. Furthermore, beta-selective mannosylation was achieved with a Crich-type donor at 0 C to ambient temperature, without donor preactivation. The donor was also used for the first step of a one-pot two-step glycosylation to obtain a trisaccharide; the second coupling involved activation of a thioglycoside with NIS/TMSOTf (NIS = N-iodosuccinimide). We believe that this offers a good alternative to current protocols.
