The 15N NMR chemical shifts of ten substituted pyridines (B) and their complexes with trifluoroacetic acid (AHB) were measured at the natural abundance level in dichloromethane.The plot of the relative chemical shifts against DeltapKa gives a titration curve which reflects a protometric equilibrium AH…B ->/<- A-...HB+.These data were used to determine the constants of the overall proton transfer reaction (Kexp).A linear relationship holds between log Kexp and DeltapKa. Deltadelta(15N) values can be treated as a good hydrogen bond parameter.KEY WORDS: 15N NMR spectroscopy, Hydrogen bond, Proton transfer, Pyridines In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model.

The heterogeneous vapor-phase alkylation of pyridine with methanol over Na+, K+, Rb+, or Cs+ exchanged X- or Y-type zeolite in an atmophere of nitrogen resulted in the formation of 2- and 4-ethylpyridines and 2- and 4-vinylpyridines together with picolines and lutidines.Next, the alkylation of alpha-, beta-, and gamma-picolines with methanol was studied over alkali cation exchanged zeolites and was found to produce mainly the side-chain methylated derivatives: ethylpyridines and vinylpyridines.However, considerable amounts of ring-alkylated derivatives (lutidines) were formed simultaneously.In general, the catalytic activity became observable under reaction conditions involving both a high temperature and a small flow rate of carrier gas (N2).The yields of ethylpyridines were highest when the CsY catalyst was used at 450 deg C, whereas the yields of vinylpyridines were highest when the CsX catalyst was used at 425 deg C.This catalytic side-chain alkylation over alkali cation exchanged zeolites was successfully applied to a variety of picolines, lutidines, and ethylpyridines with either methanol or ethanol.

Organometallic oligoamides built from three to four ferrocene amino acid units (H-Fca-OH, 1-amino-1′-ferrocene carboxylic acid) fold into hydrogen bonded secondary structures featuring eight-membered rings by cooperative hydrogen bonds. NMR studies and DFT calculations (CAM-B3LYP, LANL2DZ, IEFPCM (THF)) reveal that the organometallic zigzag foldamer structures are highly resistant toward denaturation by hydrogen bond acceptors such as dimethyl sulfoxide and 2,4-lutidine. Replacing one ferrocene amino acid unit by the organic alpha-amino acid glycine at the C-terminal end (Fca ? Gly) significantly destabilizes the secondary zigzag structure facilitating denaturation by DMSO. Highly stabilized ordered poly(Fca) architectures are very attractive for future applications of switchable hydrogen-bonded redox-active materials.

New measurements of enthalpies of solution in hexadecane and in water (DeltaH0S), and gas-hexadecane Ostwald solubility coefficients (LH) of neutral monomeric organic solutes are reported.These values, together with literature values of DeltaH0S, LH, and gas-water Ostwald solubility coefficients (LW), have been used to derive the Gibbs energies, enthalpies, and entropies of solute transfer from water to hexadecane (DeltaG0tr, DeltaH0tr, and DeltaS0tr), as well as water-hexadecane partition coefficients (as log PH).Results have been examined by the method of multiple linear regression analysis, using the equation, The s?*2 term is difficult to interpret, but the aalpha2 and bbeta2 terms can be shown to arise through hydrogen bonding of solute molecules to the bulk water that is exothermic but rather disfavoured entropically.It is shown also that the vV2 term arises due to a combination of cavity effects and general dispersion interactions in bulk water and bulk hexadecane.

Based on structural analysis of the human 2-oxoglutarate (2OG) dependent JMJD2 histone Nepsilon-methyl lysyl demethylase family, 3-substituted pyridine 2,4-dicarboxylic acids were identified as potential inhibitors with possible selectivity over other human 2OG oxygenases. Microwave-assisted palladium-catalysed cross coupling methodology was developed to install a diverse set of substituents on the sterically demanding C-3 position of a pyridine 2,4-dicarboxylate scaffold. The subsequently prepared di-acids were tested for in vitro inhibition of the histone demethylase JMJD2E and another human 2OG oxygenase, prolyl-hydroxylase domain isoform 2 (PHD2, EGLN1). A subset of substitution patterns yielded inhibitors with selectivity for JMJD2E over PHD2, demonstrating that structure-based inhibitor design can enable selective inhibition of histone demethylases over related human 2OG oxygenases.

A simple and sensitive method for the determination of short and long-chain fatty acids using high-performance liquid chromatography with fluorimetric detection has been developed. The fatty acids were derivatized to their corresponding esters with 9-(2-hydroxyethyl)-carbazole (HEC) in acetonitrile at 60C with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride as a coupling agent in the presence of 4-dimethylaminopyridine (DMAP). A mixture of esters of C1-C20 fatty acids was completely separated within 38 min in conjunction with a gradient elution on a reversed-phase C18 column. The maximum fluorescence emission for the derivatized fatty acids is at 365 nm (lambdaex 335 nm). Studies on derivatization conditions indicate that fatty acids react proceeded rapidly and smoothly with HEC in the presence of EDC and DMAP in acetonitrile to give the corresponding sensitively fluorescent derivatives. The application of this method to the analysis of long chain fatty acids in plasma is also investigated. The LC separation shows good selectivity and reproducibility for fatty acids derivatives. The R.S.D. (n = 6) for each fatty acid derivative are <4%. The detection limits are at 45-68 fmol levels for C14-C20 fatty acids and even lower levels for HPLC of Formula: C7H9N
