A novel catalytic reaction has been designed to utilize, for the first time, CO2 as a C1 feedstock in the synthesis of N-methylamines. Simple zinc catalysts, based on commercially available zinc salts and ligands, prove highly efficient in promoting both a 6 electron reduction of carbon dioxide and the formation of a C-N bond, using hydrosilanes and amines.

The inhibition of cyclooxygenase enzymes plays an important role in the treatment of inflammatory diseases. N-Hydroxy-4-(5-methyl-3-phenylisoxazol-4-yl)benzenesulfonamide (3)-a primary metabolite of the highly selective COX-2 inhibitor valdecoxib-was synthesized and stabilized as its monohydrate (3a·H2O). The anti-inflammatory properties of 3a·H2O were investigated in carrageenan-induced edema and in acute and chronic pain models. Based on our biological investigation, we conclude that N-hydroxy-valdecoxib 3a is an active metabolite of valdecoxib.

Herein, we report a heterogeneous TiO2-supported Re catalyst (Re/TiO2) that promotes various selective hydrogenation reactions, which includes the hydrogenation of esters to alcohols, the hydrogenation of amides to amines, and the N-methylation of amines, by using H2 and CO2. Initially, Re/TiO2 was evaluated in the context of the selective hydrogenation of 3-phenylpropionic acid methyl ester to afford 3-phenylpropanol (pH2 =5 MPa, =5 MPa, T=180 C), which revealed a superior performance over other catalysts that we tested in this study. In contrast to other typical heterogeneous catalysts, hydrogenation reactions with Re/TiO2 did not produce dearomatized byproducts. DFT studies suggested that the high selectivity for the formation of alcohols in favor of the hydrogenation of aromatic rings is ascribed to the higher affinity of Re towards the COOCH3 group than to the benzene ring. Moreover, Re/TiO2 showed a wide substrate scope for the hydrogenation reaction (19 examples). Subsequently, this Re/TiO2 catalyst was applied to the hydrogenation of amides, the N-methylation of amines, and the N-alkylation of amines with carboxylic acids or esters.

The intramolecular C(sp3)-H/C(sp2)-H cross-coupling of 1,3-dicarbonyl compounds has been achieved through Cp2Fe-catalyzed electrochemical oxidation.

This review summarizes the current status of knowledge on asymmetric iridium-catalyzed direct hydrogenations of acyclic and cyclic imines. An overview of the most interesting catalysts with respect to selectivity, activity and substrate scope is given, including a discussion of the effects of different reaction conditions on the enantioselectivity of imine reduction. A detailed analysis of proposed imine hydrogenation mechanisms is presented, revealing that a significant number of recent proposals suggest outer sphere mechanisms, implying that the substrate does not bind to the metal centre during the hydrogenation reaction. An intriguing question is how a high enantioselectivity can be achieved in such systems. Generally, the factors governing the stereocontrol of iridium-catalyzed direct imine hydrogenation are little studied. The mechanistic proposals that have been put forward to explain the enantiodiscrimination of selected complexes are reviewed here, showing that the stereocontrol appears to be governed by weak non-bonding interactions between the substrate and the chiral catalyst complex. These selectivity-determining interactions might be modified through coordination of solvent, additive, or product molecules to the iridium complex, providing a rationale for the effect of solvent or additives on the enantioselectivity.

Diarylmethylamido bis(phenols) have been subjected to peptide-catalyzed, enantioselective bromination reactions. Desymmetrization of compounds in this class has been achieved such that enantioenriched products may be isolated with up to 97:3 er. Mechanistically, the observed enantioselectivity was shown to be primarily a function of differential functionalization of enantiotopic arenes, although additional studies unveiled a contribution from secondary kinetic resolution of the product (to afford the symmetrical dibromide) under the reaction conditions. Variants of the tetrapeptide catalyst were also evaluated and revealed a striking observation – enantiodivergent catalysis is observed upon changing the achiral amino acid residue in the catalyst (at the i+2 position) from an aminocyclopropane carboxamide residue (97:3 er) to an aminoisobutyramide residue (33:67 er) under a common set of conditions. An expanded set of catalysts was also evaluated, enabling structure/selectivity correlations to be considered in a mechanistic light.

It is noted that the interest of developers worldwide was focused on additives of biocomponents (oxygenates and biodiesel). In Russia, where imported additives were prevalent until recently, active process of import substitution has begun. The additive demand of Russian refineries for the production of modern quality fuels is analyzed and the domestic developments are characterized. Technical solutions that offer alternatives to the use of additives are proposed.
