Available in PDF, EPUB and Kindle. Book excerpt: The discovery of new methodologies to advance the fields of synthetic organic, nanoclusters, and polymer chemistry is critical in the asymmetric synthesis of organic compounds. Particularly, catalytic asymmetric oxidation reactions are economic. The oxidation reactions provide chiral molecules and additional functionality onto the molecules for functional group manipulation. New kinds of polymers, namely chiral-substituted poly-N-vinylpyrrolidinones (CSPVPs), stabilize the bimetallic nanoclusters such as Pd/Au or Cu/Au and induce chirality. These chiral polymers wrap around the nanometer-sized (~3 nm) bimetallic nanoclusters and catalyze a number of enantioselective oxidation reactions using oxygen or hydrogen peroxide as the oxidant. Cycloalkanediols were asymmetrically oxidized by 1 atm of oxygen gas to yield the corresponding hydroxyl ketone under the catalysis of Pd/Au (3:1) - CSPVP nanoclusters. Alkenes were oxidized by Pd/Au (3:1)-CSPVP nanoclusters under 2 atmospheric of oxygen in water to give the syn-dihydroxylated products in high chemical and excellent optical yields. Various cycloalkanes underwent regio- and enantio-selective C-H oxidation with Cu/Au (3:1)-CSPVP and 30% hydrogen peroxide to produce the corresponding chiral oxo-molecules in very good to excellent chemical and optical yields. We further discovered an enantioselective desymmetrization of a,a -dialkenyl-alkanols and a,a -dialkenyl-amino acid ethyl esters to give chiral disubstituted lactones and lactams, respectively. A number of medium-sized natural products and drugs were also oxidized regioselectively to give the corresponding mono-oxygenated products. A broad-spectrum predictive C-H oxidation of complex molecules is possible. Chapter 1 mainly discussed the synthesis and characterization of the new classes of chiral substituted PVP and bimetallic nanoclusters. Chapter 2 focus on various kind of oxidation reactions by the catalysis of CSPVP stabilized bimetallic nanoclusters. Among various bioluminescence assays, firefly luciferase based bioluminescence assays are popular due to their high specific activity, low background noise and ease of use. However, it has been found that some aromatic carboxylic acid substantially inhibited the firefly luciferase reporter enzyme's activity. In order to study firefly luciferase inhibition and the proteins associated with inhibition mechanism, we designed two 6-(dimethylamino)-2-phenylisoindolin-1-one derivatives as probe molecules. The synthesis of one probe molecule is discussed in Chapter 3 and the further investigation of its inhibitory activity on firefly luciferase is being conducted by our collaborate.

Available in PDF, EPUB and Kindle. Book excerpt: This volume discusses the great potential of metal nanoparticle catalysts for complicated molecular synthesis and reviews the current progress of this field. The development of highly active and stable heterogeneous catalysts is a crucial subject in modern science. However, development of heterogeneous catalysts for fine chemical synthesis has lagged far behind those for bulk chemical process. In recent years metal nanoparticle catalysts have been of great interest in this area due to their unique activity, ease of heterogenization, and robustness. Therefore, metal nanoparticle catalysts are an excellent candidate for the above-mentioned active and robust heterogeneous catalysts and this book provides an overview of this area. The present volume summarizes recent progress on nanoparticle catalysis for various organic transformations from simple redox reactions to complex asymmetric C–C bond forming reactions and also presents seminal studies on new technologies. It comprehensively summarizes advances in metal nanoparticle catalysis across several aspects including reaction manners, mechanistic investigations and new synthetic methodologies to encourage the use of metal nanoparticle catalysts for future organic synthesis. This volume will be of interest to students, researchers and professionals focused on the next-generation of fine chemical synthesis.

Book Synopsis Catalytic Aerobic Oxidations by : Esteban Mejía
Download or read book Catalytic Aerobic Oxidations written by Esteban Mejía and published by Royal Society of Chemistry. This book was released on 2020-07-14 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidation reactions are an important chemical transformation in both academia and industry. Among the major advances in the field has been the development of catalytic processes, which are not only selective and efficient, but also allow the replacement of common stoichiometric oxidants with molecular oxygen, ideally from air at atmospheric pressure. This results in processes with higher atom efficiency, where water is the only side product in line with the principles of green chemistry. Focusing on the use of molecular oxygen as the terminal oxidant, this book covers recent advances in both heterogeneous and homogeneous systems, with and without metals and on the “taming” of the highly reactive oxygen gas by use of micro-flow reactors and membranes. A useful reference for industrial and academic chemists working on oxidation processes, as well as green chemists.
