  3. 2. Selectivity in Host-Guest Chemistry

    Författare :Gunnar Westman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes host-guest complexes with the use of a biphenyl crown ether or cyclodextrin as host. Complexes between the biphenyl crown ether and salts form phenylalanine esters were studied. LÄS MER

    Sammanfattning : At the Primary Health Care Centre in Vännäs (VPHCC), northern Sweden, a development work was implemented in 1976-1980. The overall purpose was to enhance primary health care planning. LÄS MER

  7. 5. Natural products from nonracemie building blocks : synthesis of pine sawfly pheromones

    Författare :Michael Larsson; Torbjörn Norin; Gunnar Westman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Total synthesis; diastereoselective addition; dimethylzinc; Lewis acid; alkyllithium; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis describes a number of synthetic approaches for obtaining chiral, enantiomerically pure natural products, in particular some semiochemicals. This has been accomplished by using various strategies; by starting from compounds from the chiral pool, by using chiral auxiliaries, via enzymatic resolutions or by chemical asymmetric synthesis.
