The total synthesis of bioactive calothrixin B (2) was completed which two kinds of carbazoles using three approaches. The common strategy was based on an allene-mediated electrocyclic reaction of a 6π-electron system involving one or two indole [b]-bonds

A new total synthesis of calothrixin B is described. The key step is an allene-mediated electrocyclic reaction involving the indole 2,3-bond for the construction of a suitable 4-oxygenated 2,3,4-trisubstituted carbazole ring system.
