  1. 1. Injectable and shape-retaining collagen hydrogel, crosslinked using bio-orthogonal cycloaddition chemistry

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Murtaza Sharq; [2022]
    Nyckelord :Injectable and shape-retaining collagen hydrogel; crosslinked using bio-orthogonal cycloaddition chemistry; Injicerbara och formbevarande kollagenhydrogeler; tvärbundna med bio-ortagonal cykloadditionskemi;

    Sammanfattning : Under senaste decennierna, har intresset kring implantat från naturliga och syntetiska polymerer ökat markant i samband med en ökad marknadsefterfrågan på vävnadsdonationer. Detta har lett till efterforskningen av nya in-situ formerande geler med formbevarande egenskaper in-vivo. LÄS MER

  4. 3. Generation and capturing of arynes under mechanochemical conditions

    Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - BMC

    Författare :Victor Hellgren; [2020]
    Nyckelord :Mechanochemistry; Arynes.;

    Sammanfattning : This thesis investigated whether or not it is possible to generate and capture arynes under mechanochemical conditions. The investigation covered mechanochemical parameters, as well as parameters known to influence aryne generation in solution such as crown ether and CsF loading. LÄS MER

  5. 4. Development of synthetic methodology for non-symmetric fullerene dimers

    Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - BMC

    Författare :Fredrik Barnå; [2019]
    Nyckelord :fullerene; dumbbell; Prato; rhodium catalysis; fullerene dimer; HPLC; amino acid; cyclo addition; alkylation; solubility;

    Sammanfattning : This bachelor thesis covers the initial development of a synthesis of fullerene dimers using two different types of linking reactions. Different setups for [3+2] cycloadditions to fullerenes (Prato reaction) were tested, and for that purpose, an N-alkylated amino acid was synthesised. LÄS MER

  7. 5. Developing a route towards palustrine synthesis

    L3-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Indrek Veidenberg; [2016]
    Nyckelord :organic chemistry; organisk kemi; Chemistry;

    Sammanfattning : Palustrine, a piperidine alkaloid, was retrosynthetically analyzed and two branches of a route to a key intermediate aziridine tried – namely, nitrene formation through UV irradiation and 1,3-dipolar cycloaddition. Neither approach gave any positive results. LÄS MER
