  2. 11. Construction of Five-Membered Heterocyclic Compounds via Radical Cyclization

    Author : Stefan Berlin; Lars Engman; Mario D. Bachi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; radical; cyclization; carbonylation; melatonin; pyrrolidine; pyrrolidin-3-one; tetrahydrofuran-3-one; Organisk kemi; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis describes how radical cyclization chemistry can be applied for the construction of heterocyclic compounds.In the first part, a series of electron deficient α-phenylselenenylalkenes were prepared via a PhSeCl-addition/HCl-elimination sequence. READ MORE

  4. 12. Development and Applications of Hypervalent Iodine Compounds : Powerful Arylation and Oxidation Reagents

    Author : Nazli Jalalian; Berit Olofsson; Viktor V. Zhdankin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hypervalent iodine compounds; diaryliodonium salts; oxidation; Koser s reagent; arylation; phenols; diaryl ethers; chemoselectivity; organisk kemi; Organic Chemistry;

    Abstract : The first part of this thesis describes the efficient synthesis of several hypervalent iodine(III) compounds. Electron-rich diaryliodonium salts have been synthesized in a one-pot procedure, employing mCPBA as the oxidant. Both symmetric and unsymmetric diaryliodonium tosylates can be isolated in high yields. READ MORE

  5. 13. Pilicides and Curlicides : Design, synthesis, and evaluation of novel antibacterial agents targeting bacterial virulence

    Author : Erik Chorell; Fredrik Almqvist; Stephen Hanessian; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pilicide; curlicide; anti-virulence; chaperone usher pathway; antibacterial; pili; curli; Escherichia coli; biofilm inhibitor; 2-pyridone; peptidomimetic; Organic chemistry; Organisk kemi; Bioorganic chemistry; Bioorganisk kemi; Pharmaceutical chemistry; Läkemedelskemi; Organic synthesis; Organisk syntes; Infectious diseases; Infektionssjukdomar; Biorganic Chemistry; bioorganisk kemi; Infectious Diseases; infektionssjukdomar; datorlingvistik; computational linguistics; organisk kemi; Organic Chemistry;

    Abstract : New strategies are needed to counter the growing problem of bacterial resistance to antibiotics. One such strategy is to design compounds that target bacterial virulence, which could work separately or in concert with conventional bacteriostatic or bactericidal antibiotics. READ MORE

  6. 14. Organic Reactions i Organised Media

    Author : TOMASZ WITULA; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nucleophilic substitution; mesoporous material; microemulsion; silica; lipase; Liquid crystal; alumina; entrapment.; heterogenized; titania; organic synthesis;

    Abstract : A common problem in synthetic organic chemistry is reactant incompatibility between lipophilic organic compounds and inorganic salts. The thesis reports an investigation of some organic reactions, involving incompatible substrate and nucleophile, performed in liquid crystalline phases and also in slurries of mesoporous materials with different symmetry.

  7. 15. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds

    Author : Epameinondas Tsiligiannis; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; VOC; anthropogenic; biogenic; SOA; atmospheric oxidation; organic aerosols; CIMS; FIGAERO; TMB; isoprene; HOM; organonitrates ONs ; NOx; OH; nitrate NO3 ; Go:PAM; SAPHIR;

    Abstract : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. READ MORE
