1. Green Chemistry in Chemical Education and Synthetic Applications of Sulfinamides
Sammanfattning : The preparation of chiral molecules, i.e. compounds that are not identical to their mirror image, is of great interest in the field of organic chemistry. LÄS MER
2. Aromatic Allylation via Diazotization; Application in synthesis of heterocyclic compounds
Sammanfattning : A new method for allylation of aromatic systems has been developed. A number of arylamines were converted via diazotization to the corresponding allylaromatic compounds using tert-butyl nitrite and an excess of allylic bromides with complete regioselectivity. Electron-withdrawing groups, in the aromatic moiety, were necessary to obtain good yields. LÄS MER
3. Synthesis and applications of analogues of Tröger's base as molecular tubes, receptor and ligands
Sammanfattning : Tröger’s base was synthesized for the first time in 1887. The molecule is rigid, C2-symmetric and has a 90° angle, forming a chiral hydrophobic pocket. In this thesis, the synthesis of new analogues of Tröger’s base is described. 2- and 3-halo-substituted anilines have for the first time been condensed to Tröger’s base analogues. LÄS MER
4. Synthesis of Spiro-bicyclo[2.2.2]Octane Derivatives Towards the Development of Paclitaxel Mimetics
Sammanfattning : Many of the drugs that are developed in the pharmaceutical industry have their origin in natural products. Paclitaxel, the active substance of the medicine Taxol, was found in the bark of the Pacific yew tree (Taxus brevifolia). LÄS MER
