    Sammanfattning : Chlorinated fatty acids (ClFAs) are the major contributors of extractable, organically bound chlorine in fish lipids. A known anthropogenic source of ClFAs is chlorine bleached pulp production. Additional anthropogenic sources may exist, e.g. LÄS MER

  3. 2. Asymmetric transformation of ß- and γ-functionalized alcohols : Study of combined ruthenium-catalyzed racemization and enzymatic resolution

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kinetic resolution; dynamic kinetic resolution; kinetic asymmetric transformation; dynamic kinetic asymmetric transformation; enzyme catalysis; racemization; asymmetric synthesis; chlorohydrin; cyano acetate; amino alcohol; metalloenzyme; bifunctional catalytic system; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Sammanfattning : The major part of this thesis describes the asymmetric synthesis of β- and γ-amino alcohols through the combination of ruthenium catalyzed racemization and enzymatic kinetic resolution. The dynamic kinetic resolution, DKR, protocol for chlorohydrins was improved by employing Bäckvall’s catalyst, which is a base activated racemization catalyst, in combination with Burkholderia cepacia lipase.
