Reductive etherification of aromatic aldehydes with decaborane

Aromatic aldehydes were easily convened to the corresponding ethers in methanol or ethanol using decaborane at r.t. under nitrogen in high yields.

NPY ANTAGONISTS, PREPARATION AND USES

The present invention concerns novel compounds, their preparation and their uses, therapeutic uses in particular. More specifically it concerns derivative compounds having at least two aromatic cycles, their preparation and their uses, in particular in the area of human or animal health. These compounds have an affinity for the biological receptors of neuropeptide Y, NPY, present in the central and peripheral nervous systems. The compounds of the invention are preferably NPY antagonists, and more particularly antagonists of sub-type NPY Y1, and can therefore be used for the therapeutic or prophylactic treatment of any disorder involving NPY. The present invention also concerns pharmaceutical compositions containing said compounds, their preparation and their uses, as well as treatment methods using said compounds.

Ortho-and/or meta-substituted N-alkylamino secondary para-phenylenediamine, composition for dyeing keratin fibers containing such a para-phenylenediamine, processes using this composition and uses thereof

Novel ortho and/or meta-substituted N-alkylamino secondary para-phenylenediamine compounds, a composition for dyeing keratin fibers, for example, human keratin fibers, such as hair, comprising, in a medium that is suitable for dyeing, at least one ortho- and/or meta-substituted N-alkylamino secondary para-phenylenediamine, a process for dyeing keratin fibers comprising applying the composition, uses of the composition, and a dyeing “kit” comprising the composition.

Ortho-and/or meta-substituted N-alkylhydroxylated secondary para-phenylenediamine compounds, compositions for dyeing keratin fibers comprising such compounds, and processes of dyeing therewith

The present disclosure relates to novel N-alkylhydroxylated secondary para-phenylenediamine compounds, to a composition for dyeing keratin fibers, for instance human keratin fibers such as the hair, comprising, in a medium that is suitable for dyeing, at least one ortho- and/or meta-substituted N-alkylhydroxylated secondary para-phenylenediamine, to a process for dyeing keratin fibers comprising applying this composition, and also a dyeing “kit.”

Kinetic Studies of the Methanolysis Reaction of Chloromethylated Phenols

The solvolysis of 25 differently substituted chloromethylated phenols was studied kinetically in methanol at 25 deg C.A sharp decrease of the initial reaction rate with increasing concentrations of added acids can be explained by a very fast solvolysis of the phenolate anions in comparison with the undissociated compounds.The latter show strictly first order kinetics up to high conversions and the rate constants can be partly correlated with the Jaffe relation.Highly negative values for the reaction constants ρ=-5.4 and ρ=-6.2 for ortho- and para-chloromethylated compounds show, that the undissociated phenols react according to the SN1-mechanism.However, deviations are found for compounds with strongly electron attracting substituents, which may be partly caused by an intramolecular catalytic effect of the phenolic hydroxy group in the case of the ortho-isomers. - Keywords: Methanolysis, Chloromethylated Phenols, Anchimeric Assistance
