  2. 6. Aerobic Oxidative N-Heterocyclic Carbene Catalysis via Multistep Electron Transfer - Method Development and Applications

    Author : Anton Axelsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene; asymmetric synthesis; esterification; glycerol; electron transfer mediator; green chemistry; telescoped reaction; Organocatalysis; aerobic oxidation; dihydropyranone;

    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

  6. 9. Esterification of long-chain fatty acids to cholesterol and ethanol : role of acyltransferases and carboxylesterases

    Author : Margareta A Diczfalusy; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The aim of the present thesis was to investigate esterification of long-chain fatty acids to cholesterol and ethanol. The esterification products, cholesteryl esters and ethyl esters, may under certain circumstances accumulate in some cell types and tissues and cause pathological changes. READ MORE

  7. 10. Chemo-Enzymatic Epoxidation of Unsaturated Fatty Acids
