  1. 1. Macrocyclic Carbohydrate/Amino Acid Hybrid Molecules - Synthesis and Evaluation as Artificial Receptors

    Författare :Johan Billing; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3-dipolar cycloaddition; 3-triazoles; 2; 1; molecular recognition; artificial receptors; sugar amino acids; cyclic peptides; macrocycles; Organic chemistry; Organisk kemi;

    Sammanfattning : Methods were developed for the synthesis of three different types of macrocyclic carbohydrate/amino acid hybrid molecules. In the synthesis of the first type of macrocycles, a glucosamine derivative was oxidized at C6 and the obtained sugar amino acid was coupled to tripeptides. LÄS MER

  3. 2. Valorisation of Renewable Building Blocks via Transition Metal Catalysis – Glycerol- and Amino Acid Derived Compounds in Hydrogen Borrowing and RuAAC Reactions

    Författare :Anna Said Stålsmeden; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amination; alkylation; RuAAC; 1 3-propanediol; renewable precursors; hydrogen borrowing; 1 2 3-triazole; solketal; glycerol; amino acid-derived azide;

    Sammanfattning : To a large extent, organic building blocks are today obtained from petroleum-based products. From an environmental point of view, biomass-derived compounds are more sustainable alternatives to such oil-derived molecules. The 12 principles of green chemistry describe how chemical processes can be improved in terms of sustainability. LÄS MER

  4. 3. Synthesis of Nitrogen Heterocycles via 1,3-Dipolar Cycloadditions - Method Development and Applications

    Författare :Johan Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 2D NOESY; alkyne; 3-dipolar cycloaddition; azomethine ylide; 1; CNTs; azide; sequential one-pot; SEM EDS; microwave heating; RuAAC; CuAAC;

    Sammanfattning : Because of the diverse properties displayed by nitrogen heterocycles, they are one of the most commonly used structural elements in drug discovery. Due to this variation in properties, however, the chemistry and synthetic pathway to each heterocycle is unique. LÄS MER
