  2. 1. Metal Mediated Synthesis. Synthetic and Mechanistic Investigations of Conjugate Addition and Reductive Amination

    Author : Anders Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; halosilane; all-trans-geranylgeraniol; copper reagent; primary amines; S -geranylcitronellol; iminium salt; alfa; cuprate; beta-unsaturated; lithium iodide; borane dimethyl sulfide complex; reductive amination; conjugate addition;

    Abstract : The thesis is divided into two separate parts, one treating conjugate addition and the other reductive aminations. The first part of the thesis is concerned with organocopper promoted conjugate addition to .alfa.,. READ MORE

  4. 2. Volatile organic compounds from microorganisms : identification and health effects

    Author : Anna-Sara Claeson; Anna-Lena Sunesson; Jan-Olof Levin; Steven Nordin; Bengt Järvholm; Charles Weschler; Umeå universitet; []
    Keywords : microorganisms; building materials; VOCs; MVOCs; amines; LC-MS MS; exposure; perceived air quality; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Damp building materials are subjected to degradation processes due to moisture and also microbial growth, with both of these giving rise to emissions of volatile organic compounds (VOCs) that may contribute to indoor air health problems. The overall aim of this thesis was to investigate emissions of reactive and non-reactive VOCs from damp building materials and from the microorganisms growing on them, and also to investigate the possible health impact of these compounds.

  5. 3. Transition Metal-Free O-, N- and S-Arylations with Diaryliodonium Salts

    Author : Gabriella Kervefors; Berit Olofsson; Boris Nachtsheim; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amines; hypervalent iodine; electrophilic arylation; methodology development; total synthesis; organisk kemi; Organic Chemistry;

    Abstract : This thesis concerns the development of metal-free arylation procedures using diaryliodonium salts, a non-toxic and versatile electrophilic arylating reagent, with applications to synthesize biologically relevant targets.The first part describes a transition metal-free formal synthesis of phenoxazine with an O-functionalization of a certain phenol as a key step.

  7. 5. Transition Metal- and Enzyme-Catalyzed Reactions of Primary Amines and Allylic Alcohols : Powerful Tools in the Preparation of Pharmaceutically Important Compounds

    Author : Lisa K. Thalén; Jan-Erling Bäckvall; Dirk De Vos; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dynamic kinetic resolution; racemization; catalysis; hydrogen transfer; kinetic resolution; norsertraline; alpha-methyl carboxylic acids; pipecoloxylidide; organisk kemi; Organic Chemistry;

    Abstract : Dynamic kinetic resolution (DKR) has been applied to primary amines utilizing a ruthenium catalyst and an (R)-selective lipase to provide the corresponding amides in up to 95% isolated yield and up to >99% ee. Further investigations of the chemoenzymatic DKR of amines show that it is general and can be applied to a wide range of amines. READ MORE
