| Abstract: | A biomimetic approach to calothrixin B via a hypothetical metabolite, 6-formylindolo2,3-a]carbazole, is described. The construction of a suitable indolo2,3-a]carbazole ring system was carried out using an allene-mediated electrocyclic reaction involving two b]-bonds of indoles as the key step. |
