  1. 1. Organocatalytic Domino Reactions

    University dissertation from Stockholm : Institutionen för organisk kemi

    Author : Henrik Sundén; Stockholms universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organocatalytic; domino; iminium-enamine; enamine-iminium; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : Organocatalyzed reactions involving activation strategies of ketones and aldehydes are important processes in organic chemistry. These activation strategies serve as a versatile platform for the construction of several domino reactions. READ MORE

  2. 2. New Methods for the Synthesis of Vicinal Stereocenters Palladium-Catalyzed Domino Reactions and Asymmetric Transfer Hydrogenation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Brinton Seashore-Ludlow; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; asymmetric synthesis; domino reactions; palladium-catalyzed reactions; oxindoles; amino alcohols;

    Abstract : In this thesis the synthesis of vicinal stereocenters is investigated in two distinct contexts, namely the construction of 3,3-disubstituted oxindoles and the synthesis of b-hydroxy-a-amino acids. Both scaffolds are prevalent in a range of natural products and biologically relevant compounds and, therefore, methods for their synthesis are of great import. READ MORE

  3. 3. 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
