The transformations of unactivated alkenes through C & xe001;C bond double cleavage are always attractive but very challenging. We report herein a chemoselective approach to valuable cyclic imides by a novel Cu-catalyzed geminal amino-oxygenation of unactivated C & xe001;C bonds. O-2 was successfully employed as the oxidant as well as the O-source and was incorporated into alkenyl amides via C & xe001;C bond cleavage for the efficient preparation of succinimide or glutarimide derivatives. Moreover, the present strategy under simple conditions can be used in the late-stage modification of biologically active compounds and the synthesis of pharmaceuticals, which demonstrated the potential application.

Organic molecules bearing acetoxy moieties are important functionalities in natural products, drugs, and agricultural chemicals. Synthesis of such molecules via transition metal-catalyzed C-O bond formation can be achieved in the presence of a carefully chosen directing group to alleviate the challenges associated with regioselectivity. An alternative approach is to use ubiquitous carboxylic acids as starting materials and perform a decarboxylative coupling. Herein, we report conditions for a photocatalytic decarboxylative C-O bond formation reaction that provides rapid and facile access to the corresponding acetoxylated products. Mechanistic investigations suggest that the reaction operates via oxidation of the carboxylate followed by rapid decarboxylation and oxidation by Cu(OAc)(2).

The carboxylation of sp(3)-hybridized C-H bonds with CO2 is a challenging transformation. Herein, we report a visible-light-mediated carboxylation of benzylic C-H bonds with CO2 into 2-arylpropionic acids under metal-free conditions. Photo-oxidized triisopropylsilanethiol was used as the hydrogen atom transfer catalyst to afford a benzylic radical that accepts an electron from the reduced form of 2,3,4,6-tetra(9H-carbazol-9-yl)-5-(1-phenylethyl)benzonitrile generated in situ. The resulting benzylic carbanion reacts with CO2 to generate the corresponding carboxylic acid after protonation. The reaction proceeded without the addition of any sacrificial electron donor, electron acceptor or stoichiometric additives. Moderate to good yields of the desired products were obtained in a broad substrate scope. Several drugs were successfully synthesized using the novel strategy.

The 2-(neopentylsulfinyl)aniline directing group that promotes rapid palladium-catalyzed C-H acetoxylation and alkenylation of arylacetamides has been developed. The acetoxylation reaches completion within only 40 min at 100 degrees C and leads to the bis-functionalized products. Alternatively, the reaction can be carried out at room temperature, which is beneficial for sensitive substrates. For the alkenylation, we have developed a protocol in which easily available 1-substituted cyclopropanols were employed as equivalents of vinyl ketones.

Application In Synthesis of 2-Phenylbutanoic acid. I found the field of Environmental Sciences & Ecology very interesting.

Nanosized alumina (Al2O3-NPs), a widely used nanoparticle in numerous commercial applications, is released into environment posing a threat to the health of wildlife and humans. Recent research has revealed essential roles of physicochemical properties of nanoparticles in determining their toxicity potencies. However, influence of shape on neurotoxicity induced by heterogeneous Al2O3 -NPs remains unknown. We herein compared the neurotoxicity of two shapes of gamma-Al2O3-NPs (flake versus rod) and their effects on metabolic profiles of astrocytes in rat cerebral cortex. While exposed to both shapes caused significant cytotoxicity and apoptosis in a dose-dependent manner after 72 h exposure, a significantly stronger response was observed for nanorods than for nanoflakes. These effects were associated with significantly greater ROS accumulation and inflammation induction, as indicated by increased concentrations of IL-1 beta, IL-2 and IL-6. Using untargeted metabolomics, significant alternations in metabolism of amino adds, lipids and purines, and pyrimidines were observed after exposure to both types. Moreover, changes in the metabolome caused by nanorods were significantly greater than those by nanoflakes as also indicated by physiological stress responses to ROS, inflammation, and apoptosis. Taken together, these findings demonstrated the critical role of morphology in determining toxic potencies of nanoalumina and its underlying mechanisms of toxic actions. (C) 2019 Elsevier B.V.

Little-explored hydrosilylation of ketenes promoted by main-group catalysts is reported. The boron Lewis acid tris(pentafluorophenyl)borane accelerates the slow uncatalyzed reaction of ketenes and hydrosilanes, thereby providing a convenient access to the new class of beta,beta-di- and beta-monoaryl-substituted aldehyde-derived silyl enol ethers. Yields are moderate to high, and Z configuration is preferred. The corresponding silyl bis-enol ethers are also available when using dihydrosilanes. The related trityl-cation-initiated hydrosilylation involving self-regeneration of silylium ions is far less effective.

Re-2(CO)(10) efficiently catalyzes the direct reduction of various carboxylic acids under mild conditions (rt, irradiation 350 or 395 nm). While aliphatic carboxylic acids were readily converted to the corresponding disilylacetals with low catalyst loading (0.5 mol %) in the presence of Et3SiH (2.2 equiv), aromatic analogues required more drastic conditions (Re-2(CO)(10) 5 mol %, Ph2MeSiH 4.0 equiv) to afford the corresponding aldehydes after acid treatment.

A series of five new zinc(II) complexes of 2-phenylbutyric acid comprising of one homoleptic (1) and four heteroleptic (2-5) complexes were synthesized under open beaker conditions. The behavior of the complexes in the solid and solution state was explored through FT-IR and NMR (H-1 and C-13) spectroscopy, respectively. Crystallographic data have revealed that complexes 2 and 3 crystallized in monoclinic and triclinic crystal system, respectively, with a distorted octahedral geometry, whereas complex 4 crystallized in monoclinic crystal system with a pentagonal geometry around the zinc(II) atom. All the complexes have been screened for enzyme (alkaline phosphatase) inhibition, in vitro hemolysis and antileishmanial activity, DNA and cetyl-trimethylammonium bromide (CTAB) interaction. The increase in the concentration of complexes 1, 2, 4 and 5 remarkably decreases the activity of enzyme alkaline phosphatase, whereas complex 3 was found inactive. The behavior of the complexes as a potent drug is clear from the results of hemolysis and antileishmanial activity against promastigote. The UV-Vis spectroscopic data of complexes-DNA interactions suggested a surface binding mode whereas the interaction of CTAB with complexes, studied through conductometry, confirmed strong in-teracting ability of complexes with CTAB.
