TRIAZOLE COMPOUNDS AS LIPOXYGENASE INHIBITORS

There is provided compounds of formula (I) wherein W is an optionally substituted aryl or heteroaryl group, and pharmaceutically-acceptable salts thereof, which compounds are useful in the treatment of diseases in which inhibition of the activity of a lipoxygenase (e.g. 15- lipoxygenase) is desired and/or required, and particularly in the treatment of inflammation.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.1448-87-9, you can also check out more blogs about1448-87-9

A Dual Palladium and Copper Hydride Catalyzed Approach for Alkyl?Aryl Cross-Coupling of Aryl Halides and Olefins

We report an efficient means of sp2?sp3 cross coupling for a variety of terminal monosubstituted olefins with aryl electrophiles using Pd and CuH catalysis. In addition to its applicability to a range of aryl bromide substrates, this process was also suitable for electron-deficient aryl chlorides, furnishing higher yields than the corresponding aryl bromides in these cases. The optimized protocol does not require the use of a glovebox and employs air-stable Cu and Pd complexes as precatalysts. A reaction on 10 mmol scale further highlighted the practical utility of this protocol. Employing a similar protocol, a series of cyclic alkenes were also examined. Cyclopentene was shown to undergo efficient coupling under these conditions. Lastly, deuterium-labeling studies indicate that deuterium scrambling does not take place in this sp2-sp3 cross coupling, implying that beta-hydride elimination is not a significant process in this transformation.

Metal- and Acid-Free C-H Formylation of Nitrogen Heterocycles: Using Trioxane as an Aldehyde Equivalent Enabled by an Organic-Soluble Oxidant

A metal-free, innate, and practical C-H formylation of nitrogen heterocycles using trioxane as a formyl equivalent is reported. This reaction provides a mild and robust method for modifying medicinally relevant heterocycles with an aldehyde handle. The use of an organic soluble oxidant, tetrabutylammonium persulfate, is critical in promoting the desired coupling.

Photoredox-Catalysed Decarboxylative Alkylation of N-Heteroarenes with N-(Acyloxy)phthalimides

An iridium photoredox catalyst in combination with either a stoichiometric amount of Br¡ãnsted acid or a catalytic amount of Lewis acid is capable of catalyzing regioselective alkylation of N-heteroarenes with N-(acyloxy)phthalimides at room temperature under irradiation. A broad range of N-heteroarenes can be alkylated using a variety of secondary, tertiary, and quaternary carboxylates. Mechanistic studies suggest that an IrII/IrIIIredox catalytic cycle is responsible for the observed reactivity.

Synthesis and characterization of linear 1,4-diazine-triphenylamine?based selective chemosensors for recognition of nitroaromatic compounds and aliphatic amines

Novel 1,4-diazine-based dyes of the D?pi?A type, possessing triphenylamine as an electron-donating group, have been developed. Fluorescence studies have demonstrated that emission of these fluorophores is sensitive towards different nitroaromatic compounds and aliphatic amines, both in solutions and in a vapor phase. Moreover, these compounds can be considered as ?naked-eye? fluorescent probes for solution polarity because they possess pronounced solvatochromic properties. Therefore, these compounds have to be regarded as potential multifunctional chemosensors for monitoring hazardous organic substances.
