✦ Synopsis

The oxidative cyclization of 5-(2-amino-5-methoxycarbonylphenyl)-substituted tricarbonyl[h 4 -cyclohexa-1,3-diene]iron complexes by air in protic medium provides the corresponding tricarbonyl[h 4 -4a,9a-dihydro-9H-carbazole]iron complexes. This procedure is applied to the total synthesis of the 3-methoxycarbonylcarbazole alkaloids mukonine and mukonidine.

Aryl-substituted tricarbonyl(rl4-cyclohexa -1,3-diene)iron complexes are oxidatively cyclized in protic medium in the air to tricarbonyliron-complexed 4a,9a-dihydro-9H-carbazoles. The method is applied to the total synthesis of mukonine and mukonidine.
