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

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

    Sammanfattning : 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. LÄS MER
