A new method for the synthesis of substituted pyrido[2,3-b] indoles (α-carbolines) (14, 27-31), featuring Pd-catalyzed cross coupling between pyridine and aniline derivatives and subsequent intramolecular cylization, has been developed. This method provided a highly convergent access to the tetracyclic segment (3) of the marine antitumor agents: grossularines-1 and -2 (1,2).
