Using 4-fluorophenol as a reference hydrogen-bond donor, equilibrium constants K for the formation of 1 : 1 hydrogen-bonded complexes have been obtained by FTIR spectrometry for 33 secondary amines in CCl4 and/or C2Cl4 at 298 K. A spectroscopic scale of hydrogen-bond basicity is constructed from the IR frequency shift Av(OH) of methanol hydrogen-bonded to secondary amines. The comparison of the pK(HB) (log K), Deltav(OH), and pK(a) scales points to the sensitivity of pK(HB) to steric effects, and of Deltav(OH) to the p character of the nitrogen lone pair. The pKHB scale of secondary amines extends from 2.59 for pyrrolidine to -0.45 for (Me3Si)(2)NH. The main effects explaining the pK(HB) variations are (i) the opposite polarizability and steric effects in alkylamines, (ii) field-inductive effects (e.g N drop CCH2NHMe), (iii) intramolecular hydrogen bonding, e.g. in (MeOCH2CH2)(2)NH, and (iv) the ring size giving the order: pyrrolidine = azetidine > piperidine > 2-methylaziridine > azepane. IR spectra show the attachment of 4-fluorophenol to the nitrile nitrogen of N drop CCH2NHMe and N drop CCH2CH2NHMe, to the oxygen of morpholine and (MeOCH2CH2)(2)NH, and to the sulfur of thiomorpholine and thiazolidine, in addition to attachment to the amino nitrogen. The correlation of pK(HB) with the minimum electrostatic potential on the nitrogen lone pair is used for unravelling the basicity of each nitrogen of 1-methyl-1,4-diazepane.

Storage experiments on garlic (Allium sativum L.) bulbs were conducted to elucidate the causes and prevention of green discoloration (greening) of garlic puree, a severe problem in garlic processing. Greening of the pureed bulbs increased with the accumulation of S-(E-1-propenyl)-L-cysteine sulfoxide (isoalliin), which is metabolized from N-(gamma-glutamyl)-S-(E-1-propenyl)-L-cysteine (Glu-PEC) during cold storage (3 degrees C). Greening was reduced by warm storage (> 25 degrees C) of the cold pre-stored bulbs, with an accompanying decrease in isoalliin. Accumulated isoalliin in the garlic bulbs during cold storage was converted to 5-methyl thiomorpholine-3-carboxylic acid sulfoxide (cycloalliin) with warm storage (> 25 degrees C). The relationship between warm storage conditions (temperature, duration) and decreases in isoalliin content were presumed to be applicable to a first order-Arrhenius equation. Two-week storage of the ingredient garlic bulbs at 40 degrees C, after cold pre-storage at 3 degrees C for 12 weeks, sufficiently reduced greening of the processed puree to maintain the commercial quality of the bulbs.

Metal ion dyshomeostasis is hypothesized to play a role in the toxicity and aggregation of the amyloid beta (A beta) peptide, contributing to Alzheimer’s disease (AD) pathology. We report on the synthesis and metal complexation ability of three bidentate quinoline-triazole derivatives 3-(4-(quinolin-2-yl)-1H-1,2,3-triazol-1-yl)propan-1-ol (QOH), 4-(2-(4-(quinolin-2-yl)-1H-1,2,3-triazol-1-yl)ethyl)morpholine (QMorph), and 4-(2-(4-(quinolin-2-yl)-1H-1,2,3-triazol-1-yl)ethyl)thiomorpholine (QTMorph). We further study the utility of these ligands to modulate A beta peptide aggregation processes in the presence and absence of Cu2+ ions. Ligand-peptide interactions were first investigated using both 2-D H-1-N-15 band-selective optimized flip angle short transient heteronuclear multiple quantum correlation (SOFAST-HMQC) NMR spectroscopy and molecular modeling techniques, indicating interactions with glutamic acid (E3) and several residues in the hydrophobic region of A beta. Native gel electrophoresis with western blotting along with transmission electron microscopy provided information on the ability of each ligand to modulate A beta aggregation. While the ligands alone did not modify A beta peptide aggregation at the 24 h timepoint, signifying relatively weak ligand-peptide interactions, the ligands did modify the aggregation profile of the peptide in the presence of stoichiometric and suprastoichiometric Cu. Interestingly, the thioether derivative QTMorph exhibited the most pronounced effect on peptide aggregation in the presence of Cu. Overall, the quinoline-triazole ligand series were shown to interact with the hydrophobic region of the A beta peptide, and modulate the Cu-A beta aggregation process. (c) 2016 Elsevier Inc.

The oxidative anti-Markovnikov amination of styrenes catalyzed by cationic rhodium complexes provides a new access to enamines. As catalyst precursors [Rh(cod)(amine)(2)](+) complexes have been identified and characterized for the first time by X-ray crystallography and NMR. While piperazine, N-methylpiperazine, and thiomorpholine form 1:1 Rh-amine complexes, nonchelating amines such as piperidine and diethylamine form 1:2 Rh-amine complexes. The easier dissociation of the amine ligand explains why monodentate amines give good yields of the corresponding enamines in contrast to bidentate amines. (C) 1998 Elsevier Science S.A.
