  1. 1. Dynamic Covalent Resolution: Applications in System Screening and Asymmetric Synthesis

    Författare :Pornrapee Vongvilai; Olof Ramström; Benjamin Miller; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dynamic covalent kinetic combinatorial resolution; Self-screening; Transesterification; Amidation; Enzyme catalysis; Nitroaldol reaction; Secondary alcohols; Strecker reaction; Aminonitriles; Racemase; Enzyme catalytic promiscuity; Chemistry; Kemi; Organic chemistry; Organisk kemi; Bioorganic chemistry; Bioorganisk kemi;

    Sammanfattning : Combined thermodynamic/kinetic events amount to a kinetically controlled Dynamic Combinatorial Resolution (DCR) process, where the lability of themolecules/aggregates are used to generate dynamics, and the species experiencing the lowest activation energy is selected via kinetic process. Bothinter- and intramolecular processes can be performed using this concept,resulting in complete resolution and associated amplification of the selected species. LÄS MER

  3. 2. Novel Pincer Complex-Catalyzed Transformations : Including Asymmetric Catalysis

    Författare :Juhanes Aydin; Kálmán J. Szabó; Oleg V. Ozerov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pincer; palladium; catalysis; chiral; asymmetric; palladium IV; allylation; aldol; aminoacid; C-H functionalization; cross-coupling; homoallylic; heck reaction; tridentate ligand; Chemistry; Kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis is focused on the development of new pincer complex-catalyzed transformations. Optimization of the catalytic properties (fine-tuning) was directed to increase the catalytic activity as well as the chemo-, stereo- and enantioselectivity of the complexes. LÄS MER
