    Abstract : The work centersaround perfluoroaryl azides (PFAAs), and theirability to undergo certain fast and robusttransformations. The chemistry was furtherappliedfor biomedical applications.The first section focuses on the azide-aldehyde-amine cycloaddition using PFAAs. READ MORE

  4. 2. Discovery of Small Peptides and Peptidomimetics Targeting the Substance P 1-7 Binding Site : Focus on Design, Synthesis, Structure-Activity Relationships and Drug-Like Properties

    Author : Rebecca Fransson; Anja Sandström; John S Svendsen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; substance P 1-7; peptidomimetics; structure-activity relationship; drug-like properties; phenylalanine; imidazole; MAP aryl amides; carbonylation; Pharmaceutical chemistry; Farmaceutisk kemi; Medicinal Chemistry; Läkemedelskemi;

    Abstract : Biologically active peptides are important for many physiological functions in the human body and therefore serve as interesting starting points in drug discovery processes. In this work the neuropeptide substance P 1–7 (SP1–7, H-Arg-Pro-Lys-Pro-Gln-Gln-Phe-OH), which has been demonstrated to reduce neuropathic pain and attenuate opioid withdrawal symptoms in animal models, has been addressed in a medicinal chemistry program with the overall aim of transforming this bioactive peptide into more drug-like compounds.

  6. 4. Metal‐Free Arylations of Oxygen and Nitrogen Nucleophiles : Applications of Diaryliodonium Salts

    Author : Elin Stridfeldt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; arylation; aryloxyamines; cyclization; diaryliodonium salts; O-aryloximes; sigmatropic rearrangement;

    Abstract : This thesis concerns development of new methods for metal‐free arylations in organic synthesis. The protocols discussed in the thesis are based on a class of hypervalent iodine compounds called diaryliodonium salts. These reagents are known to transfer aryl moieties to suitable nucleophiles.
