Synthesis of Unsymmetrical 2,2′-Biindolyl Derivatives by a Cu-Catalyzed N-Arylation/Pd-Catalyzed Direct Arylation Sequential Process
摘要:
A one-pot synthesis of unsymmetrical 2,2'-biindolyl derivatives through a Cu-catalyzed N-arylation/Pd-catalyzed direct arylation sequence was described. The reaction involved easily prepared o-gem-dibromovinyl substrates, and the desired biindolyls were obtained in moderate to good yields.

The synthesis of indolocarbazoles was achieved via photochemical and thermal annulation reactions of chromium Fischercarbenecomplexes. This methodology allows for facile incorporation of hydrogen bonding functionality which complements the pharmacophore contained within bioactive indolocarbazole natural products.
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.

The palladium-catalyzed intramolecular oxidative coupling reaction of 1,1'-carbonyldiindoles was achieved by using Pd(OAc)(2) and Cu(OAc)(2), producing 1,1'-carbonyl-2,2'-biindolyls, which were then converted to tjipanazoles D and I
