  1. 1. Dynamic Sulfur Chemistry : Screening, Evaluation and Catalysis

    Författare :Rémi Caraballo; Olof Ramström; Nicolas Giuseppone; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Dynamic combinatorial chemistry; dynamic sulfur chemistry; thioglycoside; mutarotation; disulfide metathesis; hemithioacetal formation; 1H STD-NMR; inhibition; phosphine; Concanavalin A; beta-galactosidase; dynamic drug discovery.; Chemistry; Kemi; Organic chemistry; Organisk kemi; Bioorganic chemistry; Bioorganisk kemi;

    Sammanfattning : This thesis deals with the design, formation and evaluation of dynamic systems constructed by means of sulfur-containing reversible reactions, in organic and aqueous media and under mild conditions. In a first part, the synthesis of thioglycoside derivatives, constituting the biologically relevant starting components of the dynamic systems, is described. LÄS MER

    Sammanfattning : This thesis is divided into six parts, all centered around the development of dynamic (i.e., reversibly interacting) systems of molecules and their applications in dynamic combinatorial chemistry (DCC) and organic synthesis. LÄS MER

  3. 3. Catalysis in Dynamic Systems: Control within Molecular Reaction Networks

    Författare :Fredrik Schaufelberger; Olof Ramström; Leonard Prins; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; systems chemistry; dynamic covalent chemistry; catalyst screening; reaction networks; organocatalysis; imine exchange; combinatorial chemistry; dynamic systemic resolution; feedback; error-correction; Morita-Baylis-Hillman reaction; C-H activation; H-bond catalysis; transamination; Kemi; Chemistry;

    Sammanfattning : Life as we know it is based on complex networks of biochemical reactions that constantly interact within large dynamic systems. The field of systems chemistry uses chemical models to study how reaction networks – and thereby life – function on a molecular level. LÄS MER

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

    Författare :Pornrapee Vongvilai; Olof Ramström; Benjamin Miller; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 5. Dynamic Systems for Screening, Control and Identification of Protein-Ligand Interactions

    Författare :Rikard Larsson; Olof Ramström; Michel R. Gagné; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dynamic combinatorial chemistry; Dynamic kinetic combinatorial resolution; Catalytic screening; Transthiolesterification; Thiol disulfide interchange; Nitroaldol reaction; Lectins; Hydrolases; Dynamic self-inhibition; Organic chemistry; Organisk kemi;

    Sammanfattning : Dynamic systems for screening, control and identification of different protein-ligand interactions are presented. Dynamic chemistry is used to produce new compounds/constituents in situ that can interact with a target molecule. Several entities can be introduced at the same time and interact with one another.
