Using N-acetyl-d-glucosamine as a starting material, the anti-influenza drugs oseltamivir and tamiphosphor were synthesized via a pivotal intermediate of aldehyde 8. An intramolecular Horner-Wadsworth-Emmons reaction was utilized to construct the highly functionalized cyclohexene ring. The existing N-acetyl group was transformed into an azido group for the subsequent aziridination, followed by implantation of a 3-pentoxy group of the desired stereochemistry.

We have recently identified a new class of high affinity ligands for CD69 leukocyte membrane receptor, carboxylated calixarenes. Of the three compounds investigated here, thiacalix[4]arene had the highest affinity for CD69 in direct binding assays, and proved to be the most specific inhibitor of CD69 identified so far in receptor precipitation and cellular activation experiments. Carboxylated calixarenes also proved effective at protection of CD69high lymphocytes from apoptosis triggered by a multivalent ligand or antibody. Thus, carboxylated calixarenes set a new paradigm for noncarbohydrate ligands for CD69 making them attractive for protection of killer cells in combined animal tumor therapies.

The structures of in catena-poly[[(di-2-pyridylamine-kappa2N, N?)silver(I)]-mu-nicotinato-kappa2N:O], [Ag(C 6H4NO2)(C10H9N 3)]n was discussed. It was found that the Ag atom is tetracoordinated by two N atoms from the di-2-pyridylamine (BPA) ligand. A polymeric chain structure was generated, which extends along [100] by bridging nicotinate N and O atoms. The results show that the ribbons were linked between inversion-related pairs of 2,6-dihydroxybenzoate ligands to generate a three-dimensional network.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 499-40-1 is helpful to your research., Reference of 499-40-1

Electric Literature of 74808-09-6, An article , which mentions 74808-09-6, molecular formula is C36H36Cl3NO6. The compound – (2R,3R,4S,5R,6R)-3,4,5-Tris(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-yl 2,2,2-trichloroacetimidate played an important role in people’s production and life.

(Chemical Equation Presented) The development of a general and practical method for the stereoselective synthesis of beta-O-aryl glycosides that exploits the nature of a cationic palladium(II) catalyst, instead of a C(2)-ester directing group, to control the beta-selectivity is described. This beta-glycosylation reaction is highly diastereoselective and requires 2-3 mol % of Pd(CH3CN)4(BF4)2 to activate glycosyl trichloroacetimidate donors at room temperature. The current method has been applied to D-glucose, D-galactose, and D-xylose donors with a nondirecting group incorporated at the C(2)-position to provide the O-aryl glycosides with good to excellent beta-selectivity. In addition, its application is widespread to electron-donating, electron-withdrawing, and hindered phenols. The reaction is likely to proceed through a seven-membered ring intermediate, wherein the palladium catalyst coordinates to both C(1)-trichloroacetimidate nitrogen and C(2)-oxygen of the donor, blocking the alpha-face. As a result, the phenol nucleophile preferentially approaches to the top face of the activated donor, leading to formation of the beta-O-aryl glycoside.
