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).
A novel organometallic complex having high reliability is provided. The organometallic complex includes platinum and a ligand coordinated to the platinum. The ligand includes a plurality of pyridoindole skeletons. Each of the pyridoindole skeletons includes nitrogen bonded to the platinum. Each of the pyridoindole skeletons is bonded to an arylene group bonded to the platinum.
