  1. 1. Regio ex machina : Om det regionala medborgarskapets villkor

    Författare :Tomas Mitander; Malin Rönnblom; Jörgen Johansson; Ulf Mörkenstam; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Regionalization; Discourse analysis; Värmland; Poststructuralist Discourse Theory; Regional Citizenship; Neoliberalism; Statsvetenskap; Political Science;

    Sammanfattning : Departing from the ongoing regionalization processes in Europe and other parts of the world, this thesis aims to study the premises and conditions of regional citizenship in contemporary state restructuring. As globalization is viewed to challenge the sovereignty and capacity of nation states, subnational regions have gained authority and interest as key actors to compete on globalized markets of capital in order to ensure future development.

  3. 2. Heck Reactions with Aryl Chlorides : Studies of Regio- and Stereoselectivity

    Författare :Gopal K. Datta; Mats Larhed; Anders Hallberg; Martin Oestreich; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heck reaction; aryl chloride; vinyl ether; regioselective; stereoselective; palladium; chelation control; microwave; Pharmaceutical chemistry; Farmaceutisk kemi;

    Sammanfattning : Homogeneous palladium-catalyzed Heck vinylation of aryl chlorides was investigated under air using Herrmann’s palladacycle and the P(t-Bu)3-liberating salt [(t-Bu)3PH]BF4. Based on the results, controlled microwave heating was utilized to accelerate model Heck reactions with aryl chlorides down to 30 min employing an electron-poor olefin and a mixture of an ionic liquid and 1,4-dioxane as solvent.

  7. 5. A Novel Rearrangement of Allyl Benzyl Ethers and Aspects on the Glyoxylate Ene Reaction

    Författare :Johan Wennerberg; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; liverwort; natural product synthesis; phenyl butyraldehydes; allyl benzyl ethers; 2-hydride migration; 1; 4-rearrangement; regio selectivity; shape selectivity; zeolite; Ene reaction; Taxol A-ring; naphthalene derivatives; dihydronaphthalenes; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis describes an improvement of the glyoxylate ene reaction by using siamyl glyoxaylate and a development of the novel rearrangement of allyl benzyl ethers. The glyoxylate ene reaction was used as a key reaction in a 8-step synthesis of a Taxol A-ring building block. LÄS MER
