Metal-catalyzed cycloaddition is an expeditious synthetic route to functionalized heterocyclic frameworks. However, achieving reactivity-controlled metal-catalyzed azide-alkyne cycloadditions from competing internal alkynes has been challenging. Herein, we report a nickel-catalyzed [3 + 2] cycloaddition of unsymmetrical alkynes with organic azides to afford functionalized 1,2,3-triazoles with excellent regio- and chemoselectivity control. Terminal alkynes and cyanoalkynes afford 1,5-disubstituted triazoles and 1,4,5-trisubstituted triazoles bearing a 4-cyano substituent, respectively. Thioalkynes and ynamides exhibit inverse regioselectivity compared with terminal alkynes and cyanoalkynes, affording 1,4,5-trisubstituted triazoles with 5-thiol and 5-amide substituents, respectively. Density functional theory calculations are performed for the elucidation of the reaction mechanism. The computed mechanism suggests that a nickellacyclopropene intermediate is generated by the oxidative addition of the alkyne substrate to the Ni(0)-Xantphos catalyst, and the subsequent C-N coupling of this intermediate with an azide is responsible for the chemo- and regioselectivity.

Post-combustion CO2 capture is considered to be the most promising technology to limit the CO2 emissions from existing fossil fuel power plants. One of the main problems associated with the CO2 capture process is the degradation of amine solvents, which can negatively impact both human health and the environment. Degradation products are formed in the liquid phase of the solvent, but can also be emitted with the gaseous effluents, increasing the need for monitoring strategies. The present review proposes a critical analysis of the literature concerning the analytical strategies developed in the field of post-combustion capture to identify and quantify the main classes of degradation products formed; specifically amines, amides, aldehydes, nitrosamines and organic acids. Regarding the liquid phase, the principal analytical methods involved are Liquid Chromatography (LC) and Gas Chromatography (GC) for the analysis of amines and Ionic Chromatography (IC) for the analysis of organic and inorganic acids. Concerning aldehydes, the most described method is derivatization of the compounds with 2,4-dinitrophenylhydrazine prior to LC analysis. In order to monitor the gaseous effluents, four methods have been described: FTIR, implementation of impingers, online MS analysis and sampling on solid sorbents.

New chloro-meta-phenylenediamines, their use as couplers in the oxidation dyeing of keratinous fibres, dyeing compositions for hair containing these compounds and dyeing process using the said compositions. The invention relates to the compounds of formula: STR1 in which Z and Z’ denote, independently of one another, an alkyl radical having from 1 to 4 carbon atoms or a hydroxyalkyl radical having from 2 to 4 carbon atoms, and R1 and R2 denote, independently of one another, a hydrogen atom, an alkyl radical having from 1 to 4 carbon atoms or a mono- or polyhydroxyalkyl radical having 2 or 3 carbon atoms, to their addition salts with an acid, and to their use by way of couplers for the oxidation dyeing of keratinous fibres, especially human hair. These compounds, when they are combined with paraphenylenediamines, surprisingly give beige to light brown hues or purple hues of greater or lesser redness, depending on the substitution of the 5-amino group of the chlorobenzene.

A series of Nalpha-benzyloxycarbonyl- and Nalpha-acyl-L-leucine(2-phenylaminoethyl)amide derivatives were prepared and evaluated for their inhibitory activity against rabbit and human cysteine proteases cathepsins K, L, and S. These data indicate that Nalpha-acyl-alpha-amino acid-(arylaminoethyl)amides represent a new class of selective non-covalent inhibitors of cathepsin K. Compounds 4b, 4e, and 4g exhibit high potency toward rabbit and human cathepsin K (IC50 < 0.006 muM) and are characterized by an excellent selectivity profile vs human cathepsins L and S.

A new Lewis acid-catalyzed atom transfer radical cyclization reaction of unsaturated alpha-bromo oxazolidinone imides is reported. In the presence of Lewis acids such as Mg(ClO4)2 and Yb(OTf)3, a series of trans cyclic products was obtained in high yield (up to 87%) between 0C and room temperature. The loading of strong Lewis acids, such as Yb(OTf)3, can be reduced to 0.1 equiv. without significantly compromising the yield. Excellent diastereoselectivity could be achieved by using 1,2-stereocontrol or a chiral oxazolidinone auxiliary. For substrates 1e and 1f bearing a beta-methyl substituent and the chiral auxiliary, (S)-(-)-4-benzyl-5,5-dimethyl-2-oxazolidinone, respectively, the diastereomeric ratio of the products was greater than 50:1.

Over the last half-century, the molecular imaging technique of positron emission tomography (PET) has emerged as an important tool for biomedical research, drug development and medical diagnosis. The power of PET derives from its utilization of radiotracers that can report specific information on pharmacology, biochemistry, and physiology. Many of these radiotracers are heterocycles that have been labeled with a short-lived cyclotron-produced radioisotope, either carbon-11 (t1/2 = 20.4 min) or fluorine-18 (t1/2 = 109.8 min). This review addresses the chemical challenges to be met in producing PET radiotracers with these radioisotope labels at heterocyclic moieties and the methods now available for doing so.

The efficient utilization of carbon dioxide (CO2) as a C1-building block in organic synthesis has attracted considerable attention in view of sustainable chemistry and green chemistry concepts. Recently, three-component reaction of amines, epoxides, and carbon dioxide has emerged as a powerful strategy for the synthesis of biologically important organic carbamates. In this review, we try to provide a comprehensive and updated overview of recent developments in this interesting research arena with special emphasis on the mechanistic aspects of the reactions. The review is divided into two major sections. The first section focuses exclusively on synthesis of acyclic carbonates, while the second covers construction of cyclic carbamates.

A novel chalcogen-mediated oxyfunctionalization mode of ynamides for the synthesis of alpha-chalcogenyl acrylamides has been developed. Independent of metal catalysts, external oxidants and additives, this mild process afforded a range of structurally diverse alpha-chalcogenyl acrylamides, including alpha-selanyl acrylamides and alpha-tellanyl acrylamides. Interestingly, diverse ynamides tolerated in this approach gave different stereoselectivities.
