Transition-Metal Complexes in Organic Synthesis. Part 36. Cyclization of Tricarbonyliron Complexes by Oxygen to 4a,9a-Dihydro-9Hcarbazoles: Application to the Synthesis of Mukonine, Mukonidine, and Pyrido(3,2,1-jk)carbazoles.

-A novel method for the cyclization of aryl-substituted iron complexes such as (III) using air in a protic medium is reported. The method allows the total synthesis of mukonine (V) and mukonidine (VI) and the preparation of the pyridocarbazole (VII). -(KNOELKER,
