The five-membered metallacycles [Ni(C-N-N?)X] have been prepared by oxidative addition of o-halo-substituted imines derived from N,N-dimethylethylenediamine, C6RnH5-nCH= NCH2CH2NMe2 to [Ni(COD)2]. The molecular structure of [NiCl{2-(CH=NCH2CH2NMe2)-3-ClC 6H3}] has been determined by a single-crystal X-ray crystallographic study. Some ionic compounds [Ni(C-N-N?)L]BF4 (L = NCMe, heterocyclic amines) were also obtained. The Ni-C bond of these complexes is inert toward insertion reactions of ethylene or PhC?CPh. The action of [Ni(COD)2] on the diamines C6RnH5-nCH2N(Me)CH2CH 2NMe2 affords highly insoluble organonickel derivatives, which by reaction with aromatic amines (L) in the presence of TlBF4 lead to the ionic derivatives [Ni(C-N-N?)L]BF4. The stabilization of organometallic Ni(III) compounds using CuCl2 as oxidant was not achieved. Coordination compounds [NiClBr(N?-N)], where N-N? = 2-ClC6H4CH2N(Me)CH2CH 2NMe2, were formed probably by reductive elimination of Ni(III) species followed by reoxidation to Ni(II).

Molar enthalpies of vaporization for five di- and two tri-methylpyridines were determined with an accuracy of 0.25 per cent, using an adiabatic vaporization calorimeter.The measurements were performed over the temperature range from 313 to 368 K for four dimethylpyridines and from 328 to 368 K for the other compounds.The results were correlated as a function of temperature, and molar enthalpies of vaporization at 298.15 K and the normal boiling temperatures were obtained by extrapolation.Molar cohesive energies were calculated from experimental values for DeltaglHm and correlated as a function of temperature.

Overproduction of NO by nNOS is implicated in the pathogenesis of diverse neuronal disorders. Since NO signaling is involved in diverse physiological functions, selective inhibition of nNOS over other isoforms is essential to minimize side effects. A series of alpha-amino functionalized aminopyridine derivatives (3-8) were designed to probe the structure-activity relationship between ligand, heme propionate, and H4B. Compound 8R was identified as the most potent and selective molecule of this study, exhibiting a K i of 24 nM for nNOS, with 273-fold and 2822-fold selectivity against iNOS and eNOS, respectively. Although crystal structures of 8R complexed with nNOS and eNOS revealed a similar binding mode, the selectivity stems from the distinct electrostatic environments in two isoforms that result in much lower inhibitor binding free energy in nNOS than in eNOS. These findings provide a basis for further development of simple, but even more selective and potent, nNOS inhibitors.

Linear relationships between sspKa values in acetonitrile-water mixtures and wwpKa values in pure water have been established for five families of compounds: aliphatic carboxylic acids, aromatic carboxylic acids, phenols, amines, and pyridines. The parameters (slope and intercept) of the linear correlations have been related with acetonitrile-water composition. The proposed equations allow accurate estimation of the pKa values of any member of the studied families at any acetonitrile-water composition up to 60% of acetonitrile in volume (100% for pyridines). Conversely, the same equations can be used to estimate aqueous pKa values from chromatographic pKa values obtained from any acetonitrile-water mobile phase between the composition range studied. Estimation of pKa values have been tested with chromatographic literature data.

A fluoro derivative can be produced by reacting a hydroxy derivative with sulfuryl fluoride (SO2F2) in the presence of an organic base or in the presence of an organic base and a salt or complex composed of an organic base and hydrogen fluoride. This process enables to advantageously produce an optically active fluoro derivative (e.g., a 4-fluoroproline derivative, a 2′-deoxy-2′-fluorouridine derivative and an optically active alpha-fluorocarboxylate ester derivative) which is an important intermediate for the production of a pharmaceutical or agricultural agent or an optical material, even in large quantity without using a perfluoroalkanesulfonyl fluoride which is undesirable for industrial applications.

The stability of living polyisobutylene chains (PIB) obtained by di- and monofunctional initiators in conjunction with TiCl4 coinitiator was investigated under monomer starved conditions (i. e. after 100 % monomer conversion) in the absence and presence of different additives, such as N,N-dimethylacetamide (DMA), 2,6-di-tert-butylpyridine (DtBP), pyridine (Py) and 2,4-dimethylpyridine (DMPy), in CH2Cl2/hexane (40:60 v/v) mixture at -78 C. Only negligible amounts of chain ends with expected double bonds were formed as verified by 1H NMR, and all the additives, with the exception of DtBP, resulted in constant molecular weights for a period of four hours. However, chain coupling occurred in the presence of DtBP. On the basis of our experimental findings this effect is interpreted by proton abstraction in a reaction between DtBP and propagating chains leading to external double bonds which further react with active chain ends. Molecular weight distribution data indicate that there are differences among the examined nucleophilic compounds in their mode of action during living polymerization of isobutylene.

Spermidine alkaloids are polyaminated macrocycles containing a lactam ring, which are biosynthetically derived from L-Orn or L-Arg via putrescine intermediates. The presence of these polyamines in nature is very limited, occurring in only a few plant families, and therefore the isolation of spermidine alkaloids serves chemotaxonomic purposes. The interest in the isolation and synthesis of these alkaloids also results from the structural complexity and broad range of bioactivity attributed to these macrocyclic structures. In recent years, several research groups have been dedicated to these triaminated compounds and previously unknown natural products, or already described structures in new plant species, with potential biological applications have been reported. Novel synthetic strategies and the application of more recent synthetic methodologies have allowed new perspectives for the development of new bioactive molecules. The latest progress on the isolation, identification, biological activity, and chemical synthesis of spermidine alkaloids is summarized in this review.
