  1. 1. Amine Transaminases in Multi-Step One-Pot Reactions

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mattias Anderson; KTH.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biocatalysis; enzyme; amine transaminase; ω-transaminase; amination; primary amine; chiral amine; chemoenzymatic; green chemistry; synthesis; cascade; Biotechnology; Bioteknologi;

    Abstract : Amine transaminases are enzymes that catalyze the mild and selective formation of primary amines, which are useful building blocks for biologically active compounds and natural products. In order to make the production of these kinds of compounds more efficient from both a practical and an environmental point of view, amine transaminases were incorporated into multi-step one-pot reactions.

    Abstract : Förfrågan efter nya och mer avancerade applikationer är en pågående process vilket leder till en konstant utveckling av nya material. För att förstå relationen mellan en applikations egenskaper och dess sammansättning krävs full förståelse och kontroll över materialets uppbyggnad. READ MORE

  3. 3. Bridging McMurry and Wittig in One-Pot Olefins from Stereoselective, Reductive Couplings of Two Aldehydes via Phosphaalkenes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Juri Mai; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbonyl olefination; reductive aldehyde coupling; stereoselective; organophosphorus; phosphaalkene; phosphanylphosphonate; Wittig; Horner-Wittig; Horner-Wadsworth-Emmons; McMurry; Kemi; Chemistry;

    Abstract : The formation of C=C bonds is of great importance for fundamental and industrial synthetic organic chemistry. There are many different methodologies for the construction of C=C bonds in the literature, but currently only the McMurry reaction allows the reductive coupling of two carbonyl compounds to form alkenes.

  5. 5. Efficient and High-Yielding Routes to Diaryliodonium Salts

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Marcin Bielawski; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hypervalent Iodine Compounds; One-Pot Synthesis; Regiospecific Synthesis; Aromatic Substitution; Aryl Iodides; Arenes; Boronic Acids; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi;

    Abstract : This thesis summarizes three novel and general reaction protocols for the synthesis of diaryliodonium salts. All protocols utilize mCPBA as oxidant and the acids used are either TfOH, to obtain triflate salts, or BF3•Et2O that gives the corresponding tetrafluoroborate salts in situ. READ MORE
