ResumoTFA-induced dimerization of indole-3-acetic acid (IAA) gave 5a. The corresponding methyl ester gave the diester 5b or the lactam 6. Similar treatment of the 2,3-bis-(3-indolyl)-succinic ester 4b gave the tetrahydroindolo[2,3-a]carbazole derivative 10. The relation of these compounds to indolocarbazole alkaloids is discussed.
