  1. 1. A Regio- and Stereodivergent Route to All Isomers of vic-Amino Alcohols

    University dissertation from Stockholm : Kemi

    Author : Berit Olofsson; [2002]
    Keywords : amino alcohols; vinylepoxides; vinylaziridines; oxazolines; oxazolidinones; ring-opening; regioselective; diastereoselective; sphingosine; configuration; NMR spectroscopy;

    Abstract : The first part of this thesis describes a synthetic strategythat provides all eight possible isomers of a given vic-aminoalcohol starting from vinylepoxides. The value of a generalroute is evident, as several isomers are needed ininvestigations of structure-activity relationships forpharmacologically active derivatives, and for optimizing theperformance of chiral ligands containing the amino alcoholmoiety.

    Abstract : The main focus of this thesis has been directed towards preparation and oxidative carbocyclization of en-, dien- and aza-enallenes.In the first part of this thesis, a stereoselective oxidative carbocyclization of dienallenes was realized. READ MORE

  3. 3. Development of Aerobic Oxidative N-Heterocyclic Carbene Catalysis via Multistep Electron Transfer and its Application

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Anton Axelsson; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dihydropyranone; Michael addition; kinetics.; aerobic oxidation; acylation; N-heterocyclic carbene; green chemistry; Organocatalysis; electron transfer mediator; asymmetric synthesis;

    Abstract : Oxidation reactions are ubiquitous in synthetic chemistry, but generally suffer from formation of large amounts of potentially toxic byproducts. Aerial oxygen represents an ideal oxidant since it is inexpensive, non-toxic and only forms water as a byproduct. READ MORE

  4. 4. N-Heterocyclic Carbene Catalysis in Organic Synthesis - A Green Chemistry Approach

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Linda Ta; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aerobic oxidation; ionic liquid; sustainability; NHC catalysis; oxidative NHC catalysis; green chemistry; OTHO; Organocatalysis;

    Abstract : The twelve principles of green chemistry were created as a response to the multiple environmental issues caused by the release of waste from the chemical industry. The principles acts as a guide in the development of sustainable chemical processes for the syntheses of important molecules needed to sustain our living standards. READ MORE
