Radical Photochemical Reactions

An improved synthesis of 2,2′-biindolyl (1) is described. Derivatives of 1 with a variety of substituents in the 3,3′-positions, such as the 3,3′-diformyl derivative 19 have been synthesized. Potential syntheses of indolocarbazole alkaloids from such derivatives are outlined.
