  2. 1. Iodotrimethylsilane-Promoted Conjugate Addition of Organocopper Reagents, DDQ oxidation of Arylpropenes and Synthesis of 2-Arylcoumarans

    Author : Tommy Iliefski; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 2; DDQ; arylcoumaran; cinnamaldehyde; 6-dicyanobenzoquinone; iodotrimethylsilane; copper acetylides; 1; 3-dichloro-5; neolignan; 4-addition; arylpropene; TMSI; organocopper; conjugate addition;

    Abstract : This thesis is divided into three parts: conjugate additions of organocopper reagents, DDQ oxidations of arylpropenes, and synthesis and steric assignment of 2-arylcoumarans. The iodotrimethylsilane(TMSI)-promoted conjugate addition of alkylcopper and copper acetylides to certain a,b-unsaturated carbonyl compounds is investigated. READ MORE

  4. 2. New Applications of Monoorganocopper/Iodotrimethylsilane Reagents in Conjugate Additions

    Author : Magnus Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; beta-unsaturated; halosilane; conjugate addition; alpha; copper iodide; copper acetylides; organocopper; iodotrimethylsilane; Claisen rearrangement;

    Abstract : The thesis reports new applications of monoorganocopper compounds, RCu(LiI), and iodotrimethylsilane in conjugate additions. The present investigation demonstrates conjugate addition of alkylcopper compounds and iodotrimethylsilane to reactive .alpha.,. READ MORE

  6. 4. Mechanistic Studies of Organocopper Chemistry by NMR Spectroscopy: Conjugate Additions to Alkynes and Alkenes

    Author : Karolina Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cyanocuprate; organocopper reagents; ynones; lithium dimethylcuprate; 13C and 15N NMR spectroscopy; pi-complexes; mechanism; enoates; 6Li; 1H-HOESY; ynoates; conjugate addition;

    Abstract : This thesis focuses on the mechanisms of organocopper reactions, in particular the reactions with activated alkynes (ynoates and ynones). These reactions are of interest in the formation of new highly functionalized double bonds with control of the stereochemistry. READ MORE

  7. 5. 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
