  5. 3. Synthesis of indolocarbazoles, bisindoles and related sulfur containing systems

    Author : Tomasz Janosik; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Alkaloids; bisindoles; dithiins; indoles; indolocarbazoles; metallation; pentathiepins; polysulfides; tetrathiocins; thionation; X-ray crystallography.;

    Abstract : This thesis is focussed mainly on the synthesis and reactions of various indolocarbazoles, bisindoles and related sulfur containing systems, all possessing structural features present in many biologically active, natural or synthetic compounds. In the first part, synthetic routes towards the planar, pentacyclic ring systems of indolo[2,3-c]earbazole and indolo[3,2-a]carbazole are described. READ MORE
