  1. 1. Synthesis of O-linked Carbasugar Analogues of Galactofuranosides and N-linked Neodisaccharides

    Author : Jens Frigell; Ian Cumpstey; George Fleet; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbasugar; galactofuranose; mycobacterium; tuberculosis; ring-closing metathesis; GlfT2; galactan; epoxide-opening; pseudodisaccharide; etherification; regioselective; carbohydrate; carbocycles; glycomimetics; glucosidase; neodisaccharides; Mitsunobu; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Abstract : In this thesis, carbohydrate mimicry is investigated through the syntheses of carbohydrate analogues and evaluation of their inhibitory effects on carbohydrate-processing enzymes. Galactofuranosides are interesting structures because they are common motifs in pathogenic microorganisms but not found in mammals. M. READ MORE

  2. 2. Expanding the H-phosphonate and H-phosphonothioate chemistry towards biologically important phosphate analogs

    Author : Gaston Lavén; Jacek Stawinski; Wojciech T. Markiewicz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phosphonate; phosphonothioate; H-phosphonate; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis focuses on chemical transformations of H-phosphonate and H-phosphonothioate and can be divided in two parts. The first part, is devoted to the development of the palladium-catalyzed P-C bond formation. Both mechanistic and synthetic studies of the transformations have been performed. READ MORE

  3. 3. Synthesis of oligosaccharides related to the capsular polysaccharide of Neisseria meningitidis serotype A

    Author : Peter Teodorovic; Stefan Oscarson; Mikael Elofsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Abstract : In order to find suitable stable vaccine candidates against Neisseria meningitidis group A, several structures related to the capsular polysaccharide have been synthesised. The first part of the thesis describes the synthesis of C-phosphonate analogues starting from glucose. READ MORE

  4. 4. Synthesis of Potential Inhibitors Against HIV

    Author : Johanna Wachtmeister; Jan Kihlberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Abstract : This thesis describes the syntheses of various potential inhibitors of HIV, e.g. some 3´-hydroxymethyl-substituted carbocyclic nucleoside analogues as reverse transcriptase inhibitors and some symmetry-based peptidomimetics as protease inhibitors. READ MORE

  5. 5. Synthesis of Carbohydrate Mimics and Development of a Carbohydrate Epimerisation Method

    Author : Clinton Ramstadius; Ian Cumpstey; Robert Madsen; Stockholms universitet; []
