    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Alkaloids; bisindoles; dithiins; indoles; indolocarbazoles; metallation; pentathiepins; polysulfides; tetrathiocins; thionation; X-ray crystallography.;

    Sammanfattning : 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. LÄS MER
