A document type is Article, introducing its new discovery.

A series of heteroleptic cobalt(II) complexes of diimine and pyridonate ligands have been synthesized from cobalt(II) acetate, with the general stoichiometric formula [Co(xhp)2L] [xhp = 6-methyl- (mhp), 6-chloro-(chp), 6-bromo- (bhp) or 6-fluoro-2-pyridonate (fhp); L = 2,2?-bipyridyl (bipy), 4,4?-dimethyl-2,2?-bipyridyl (dmbipy), 1,10-phenanthroline (phen) or di-2-pyridylamine (Hdpa)]. Four have been characterised by X-ray crystallography. The compounds [Co(mhp)2(phen)], [Co(chp)2(Hdpa)]¡¤H2O and [Co(bhp)2(dmbipy)] crystallise as mononuclear species containing six-co-ordinate cobalt sites. The co-ordination geometry of the metal is distorted due to the small bite angle of the chelating xhp ligands. The fourth complex, [{Co(mu-fhp)-(fhp)(dmbipy)}2], crystallises as a dinuclear unit with the cobalt atoms bridged by the exocyclic O atom of one fhp ligand. The Co … Co distance is 3.208(6) A. A fifth complex, [{Co(mu-bhp)(O2CMe)(dmbipy)}2], has been characterised in which two cobalt atoms are bridged by the O atom from a bhp ligand, giving a Co … Co separation of 3.158(4) A. The NMR studies of the complexes [Co(xhp)2(dmbipy)] revealed large paramagnetic shifts, especially for the 6,6?-protons of the dmbipy unit. The magnitude of the shift varies depending on the pyridonate ligand used, with the largest shifts found for fhp and the smallest for mhp. This shift correlates with the basicity of the N-donor atom of the xhp ligands and hence with the co-ordinative ability of the pyridonate ligands. The synthesis of 6-fluoro-2-pyridone (Hfhp) is reported for the first time.

Electric Literature of 14215-68-0. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide

Pyridylamination is a versatile method for fluorescence labeling of oligosaccharides. The technique affords sensitive detection of saccharides with reducing termini and high-resolution separation by high-performance liquid chromatography. The conventional method, based on a liquid-phase reaction, has been extensively used in various aspects of glycobiology and glycotechnology. Unfortunately, the necessity for removing excess 2-aminopyridine makes the technique both laborious and time-consuming. Furthermore, removal of excess reagent can result in a significant loss of short saccharide components. In the present paper, we report an alternative methodology based on a “gas-phase” reaction, in which dried saccharides are reacted with vaporized 2-aminopyridine. The resultant Schiff base was also reduced in the gas phase within the same reaction microtube using a purpose-built device. The newly developed procedure was applied to both monosaccharide (GlcNAc) and oligosaccharides (isomalto-oligosaccharides) at quantitative yields with no requirement to remove excess reagent. The acid-labile sialyl linkages of alpha2-6-disialobiantennary oligosaccharides proved to be fully stable during the procedure. The developed method was also successfully applied to profiling N-linked oligosaccharides liberated from glycoproteins by hydrazinolysis and, thus, should contribute to various fields of glycomics.

The regiochemical control of the ring opening of epoxides bearing polar remote functionalities, through chelation processes assisted by metal ions, was verified in the title compound (4).The use of metal assisted procedures in several ring opening reactions of 4 leads to a modification of the regiochemical outcome, and the attack of the nucleophile on the C-4 oxirane carbon is highly favored.

Antagonists of peripheral type 1 cannabinoid receptors (CB1) may have utility in the treatment of obesity, liver disease, metabolic syndrome and dyslipidemias. We have targeted analogues of the purine inverse agonist otenabant (1) for this purpose. The non-tissue selective CB1 antagonist rimonabant (2) was approved as a weight-loss agent in Europe but produced centrally mediated adverse effects in some patients including dysphoria and suicidal ideation leading to its withdrawal. Efforts are now underway to produce compounds with limited brain exposure. While many structure-activity relationship (SAR) studies of 2 have been reported, along with peripheralized compounds, 1 remains relatively less studied. In this report, we pursued analogues of 1 in which the 4-aminopiperidine group was switched to piperazine group to enable a better understanding of SAR to eventually produce compounds with limited brain penetration. To access a binding pocket and modulate physical properties, the piperazine was functionalized with alkyl, heteroalkyl, aryl and heteroaryl groups using a variety of connectors, including amides, sulfonamides, carbamates and ureas. These studies resulted in compounds that are potent antagonists of hCB1 with high selectivity for hCB1 over hCB2. The SAR obtained led to the discovery of 65 (Ki = 4 nM, >1,000-fold selective for hCB1 over hCB2), an orally bioavailable aryl urea with reduced brain penetration, and provides direction for discovering peripherally restricted compounds with good in vitro and in vivo properties.

This work describes our preliminary efforts towards the development of aryl glucuronides as potential probes for heparanase. During the course of these initial investigations, attempted glycosidation of methyl 2,3,4-tri-O-acetyl- alpha-d-glucopyranosyluronate trichloroacetimidate with 4-hydroxycinnamic acid gave a complex mixture of four different components. These were identified as the 1-cinnamyl glucuronate ester 13, the cinnamyl linked disaccharide 14, the glucuronate trichloroacetamide 15, and the glucuronyl alpha-fluoride 16. This paper rationalises the formation of each of these products, and reports our efforts in trying to optimise the formation of the alpha-fluoride 16.
