Bridged-ring Nitrogen Compounds. Part 3. Synthesis of Representatives of the 1,5-Methano-4-benzazonine Ring System

Reaction of arylaldehydes with 2,4-dimethylpyridine and n-butyl-lithium gives in good yield 1-aryl-2-(4-methylpyridyl)ethanols which, after dehydration with polyphosphoric acid and catalytic hydrogenation, give 2-phenethyl-4-methylpyridines.Cyclisation of the derived tetrahydropyridines gives 1,4-dimethyl-2,3,4,5,6,7-hexahydro-1,5-methano-1H-4-benzazonines except when cyclisation is attempted meta to a methoxy-group.

Deprotonation effect of tetrahydrofuran-2-carbonitrile buffer gas dopant in ion mobility spectrometry

Rationale When dopants are introduced into the buffer gas of an ion mobility spectrometer, spectra are simplified due to charge competition. Methods We used electrospray ionization to inject tetrahydrofuran-2-carbonitrile (F, 2-furonitrile or 2-furancarbonitrile) as a buffer gas dopant into an ion mobility spectrometer coupled to a quadrupole mass spectrometer. Density functional theory was used for theoretical calculations of dopant-ion interaction energies and proton affinities, using the hybrid functional X3LYP/6-311++(d,p) with the Gaussian 09 program that accounts for the basis set superposition error; analytes structures and theoretical calculations with Gaussian were used to explain the behavior of the analytes upon interaction with F. Results When F was used as a dopant at concentrations below 1.5 mmol m-3 in the buffer gas, ions were not observed for alpha-amino acids due to charge competition with the dopant; this deprotonation capability arises from the production of a dimer with a high formation energy that stabilized the positive charge and created steric hindrance that deterred the equilibrium with analyte ions. F could not completely strip other compounds of their charge because they either showed steric hindrance at the charge site that deterred the approach of the dopant (2,4-lutidine, and DTBP), formed intramolecular bonds that stabilized the positive charge (atenolol), had high proton affinity (2,4-lutidine, DTBP, valinol and atenolol), or were inherently ionic (tetraalkylammonium ions). Conclusions This selective deprotonation suggests the use of F to simplify spectra of complex mixtures in ion mobility and mass spectrometry in metabolomics, proteomics and other studies that generate complex spectra with thousands of peaks.

Synthesis and Antitumor Activity of 3- and 5-Hydroxy-4-methylpyridibe-2-carboxaldehyde Thiosemicarbazones

To develop an alpha-(N)-heterocyclic carboxaldehyde thiosemicarbazone with clinical utility as an anticancer agent, two analogues, 3-hydroxy-4-methylpyridine-2-carboxaldehyde thiosemicarbazone (3-HMP) and 5-hydroxy-4-methylpyridine-2-carboxaldehyde thiosemicarbazone (5-HMP), of 5-hydroxypyridine-2-carboxaldehyde thiosemicarbazone (5-HP) have been designed and synthesized by two different methods. 3-HMP and 5-HMP both showed better antitumor activity than their respective parent compounds, 3-hydroxypyridine-2-carboxaldehyde thiosemicarbazone and 5-HP, in mice bearing the L1210 leukemia.

Recent developments in green membrane-based extraction techniques for pharmaceutical and biomedical analysis

Monitoring of target analytes (e.g., pharmaceuticals, endogenous compounds) present in biological samples usually requires a preliminary step toward analyte isolation from surrounding matrix and enrichment for trace analysis. Evident developments have been recently made to introduce novel ?green? analytical approaches (which keep the requirements of Green Analytical Chemistry ? GAC) being effective, economical, eco-friendly, and amenable to hyphenated analytical instrumentations. Modern membrane-based extraction techniques provide the smart options against classical sample preparations e.g., liquid-liquid extraction (LLE).These approaches are more stable and allow trace determination of analytes in complex matrices (e.g., biological samples), with high extraction recovery and selectivity. Simultaneously, drawbacks of LLE such as large consumption of organic solvents and the need for tedious handling are eliminated. This paper thoroughly overviews important features and applications of membrane- based extraction techniques with special focus on pharmaceutical and biomedical analysis since 2013. Different driving forces of mass transfer across the membrane were summarized and membrane-based extraction techniques were described along with their advantages/disadvantages as well.

Catalytic C-H bond addition of pyridines to allenes by a rare-earth catalyst

The catalytic C-H addition of pyridines to allenes has been achieved for the first time by using a half-sandwich scandium catalyst, thus constituting a straightforward and atom-economical route for the synthesis of alkenylated pyridine derivatives. The reaction proceeded regio- and stereoselectively, affording a new family of alkenylated pyridine compounds which are otherwise difficult to synthesize. A cationic Sc-eta2-pyridyl species was isolated and confirmed to be a key catalyst species in this transformation.

Coupling of aryl halides with aryl boronic acids with P(C6H5)(2-C6H4Cl)2 as the supporting ligand

The chlorinated triarylphosphine P(C6H5)(2-C6H4Cl)2 (1) has been used as a supporting ligand in the Suzuki-Miyaura coupling of aryl boronic acids with aryl halides. Aryl bromides without ortho substituents were successfully coupled at room temperature, while reactions involving sterically hindered aryl bromides required slight heating (70C). Electron-deficient aryl chlorides were also successfully coupled with heating (90C). Key reaction parameters such as order of addition, choice of mineral base, solvent volume, temperature, 1/Pd ratio, as well as electronic and steric variation of the aryl halide have been investigated and are reported.

A novel water-soluble highly selective ?switch-on? ionic liquid-based fluorescent chemi-sensor for Ca(II)

A novel chemi-sensor involve new bis-ionic Schiff base sensor (BISBS), N,N?-bis-[5-((2,4-lutidiniumchloride)methylene)-3-methoxysalicylidene]-R,R-1,2-cyclohexanediimine, has been synthesized and characterized. BISBS chemi-sensor was designed based on internal charge transfer (ICT) fluorescence mechanism. This new water soluble chemi-sensor provides great selectivity fluorescence detection for Ca(II) ions in an important physiological pH range. Moreover, the interaction of Ca(II) with the deprotonated BISBS to produce a metal-ligand complex with a ratio of (1: 1) accompanying with an enhancement in the intensity of emission band located at 502?nm. Fluorescence switching-on during the chemical interaction between BISBS and Ca(II) ions is very easily noticed with naked eye, but other metal cations such as alkali, alkaline earth and transition metal don’t give any fluorescence changes. The novel developed BISBS sensor successively offers low limit of detection (LOD) 1.5?nM and fast tracing of Ca(II) in the physiological pH?7.6. Thus BISBS may provide a novel auspicious methodology for detection calcium cations in the environmental and biological samples.
