  2. 1. Transition metal-catalyzed allylic and vinylic functionalization : Method development and mechanistic investigations

    Author : Johanna M. Larsson; Kálmán J. Szabó; Dennis G. Hall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palladium; copper; catalysis; Heck reaction; C-H functionalization; allylic substitution; silylation; borylation; trifluoromethylation; fluorination; mechanistic study; transition metal; alkene; allylic silane; allylic boronate; allylic fluoride; organisk kemi; Organic Chemistry;

    Abstract : The use of small molecule building blocks in, for example, pharmaceutical research and new material development, creates a need for new and improved organic synthesis methods. The use of transition metals as mediators and catalysts opens up new reaction pathways that have made the synthesis of completely new compounds possible as well as greatly improved the synthetic routes to known compounds.

  4. 2. Copper and Palladium-Mediated Transformationsof Allylic and Propargylic Substrates

    Author : Tony S. N. Zhao; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is focused on the development of new palladium and copper-mediated reactions for functionalization of alkenes and propargylic alcohol derivatives. We have developed an efficient procedure for the synthesis of allenyl and propargyl boronate from propargylic carbonates and acetates. READ MORE

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

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

    Abstract : 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. READ MORE
