  1. 1. Development of new Catalytic Methods for the Selective Synthesis of Heterocycles

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Stalin Reddy Pathi Pati; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalysis; indium; heterocycles; Lewis acid; multicomponent reactions; furans; alkynes; Organic Chemistry; organisk kemi;

    Abstract : In the field of organic chemistry, the development of new catalytic methods for the synthesis of complex molecules from simple precursors is a top priority. The main focus of this thesis concerns the diastereoselective synthesis of heterocyclic compounds using main group elements as Lewis acid catalysts. READ MORE

  2. 2. Palladium(0)-Catalysed Carbonylative Multicomponent Reactions Synthesis of Heterocycles and the Application of Quinolinyl Pyrimidines as Enzyme Inhibitors

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Linda Åkerbladh; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Palladium catalysis; Carbonylation; Multicomponent reactions; Domino reactions; Heterocycles; 4-Quinolones; 2-Aminoquinazolinones; Benzoxazinones; N-Acylguanidines; Type II NADH dehydrogenase; NDH-2;

    Abstract : Palladium-catalysed carbonylative multicomponent reactions have proven useful for the synthesis of structurally diverse compounds. Carbon monoxide serves as an atom-efficient, one-carbon building block, which allows for further structural elaboration of the carbonyl compound. READ MORE

  3. 3. Direct Catalytic Nucleophilic Substitution of Non-Derivatized Alcohols

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Anon Bunrit; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nucleophilic substitution; catalysis; alcohols; stereospecific; Lewis acid; Brønsted acid base; bifunctional; heterocycles; Organic Chemistry; organisk kemi;

    Abstract : This thesis focuses on the development of methods for the activation of the hydroxyl group in non-derivatized alcohols in substitution reactions. The thesis is divided into two parts, describing three different catalytic systems. READ MORE

  4. 4. Novel monogalactoside galectin inhibitor scaffolds : Guiding selectivity with heteroaromatic interactions

    University dissertation from Lund University, Faculty of Science

    Author : Alexander Dahlqvist; Lunds universitet.; Lund University.; [2019-04-25]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galectin; Galectin inhibitor; Heterocycles; C-glycoside; Medicinal chemistry; Organic chemistry; Hydroboration; Diastereoselective; Galactose;

    Abstract : Carbohydrates are involved in many cellular processes, and most biomolecules are glycosylated. Thesemodifications are used in biological systems as information carriers, helping regulate organization on the cell surfaceand interactions between cells and the environment. READ MORE

  5. 5. Ruthenium-catalyzed C-H Functionalization of (Hetero)arenes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karthik Devaraj; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalysis; C-H activation; heterocycles; ruthenium; aryne precursor; silylation; gramine;

    Abstract : This thesis concerned about the Ru-catalyzed C-H functionalizations on the synthesis of 2-arylindole unit, silylation of heteroarenes and preparation of aryne precursor.In the first project, we developed the Ru-catalyzed C2-H arylation of N-(2-pyrimidyl) indoles and pyrroles with nucleophilic arylboronic acids under oxidative conditions.
