  1. 1. Carboligation using the aldol reaction : A comparison of stereoselectivity and methods

    Författare :Derar Al-Smadi; Mikael Widersten; Ulf Nilsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aldol reaction; cinchonine; FSA enzyme; homologation reactions; phenylacetaldehyde derivatives; samarium diiodide.;

    Sammanfattning : The research summarized in this thesis focuses on synthesizing aldehyde and aldol compounds as substrates and products for the enzyme D-fructose-6-aldolase (FSA). Aldolases are important enzymes for the formation of carbon-carbon bonds in nature. LÄS MER

  3. 2. Synthesis of chiral allyl and propargyl boronates by organocatalytic carbene insertion to carbon-boron bonds

    Författare :Marie Deliaval; Kálmán Szabó; Fahmi Himo; Carlos Valdés; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boron; asymmetric synthesis; organocatalysis; allylic compounds; allenols; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis describes the development of a novel organocatalytic method for the synthesis of chiral allyl- and propargyl- organoboron compounds with high enantioselectivity. These organoboron species are versatile building blocks in asymmetric synthesis.We have developed a new efficient homologation method of alkenyl boronic acids. LÄS MER
