The synthesis of indolocarbazoles containing hydrogen bonding functionality mimicking the pharmacophore contained within bioactive indolocarbazole natural products is reported. The indolocarbazoles are prepared via palladium catalyzed cross coupling of indoles followed by photochemical and thermal annulation reactions of chromium carbene complexes.

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.

Differentially substituted indolocarbazoles are readily prepared via a synthetic route employing two palladium catalyzedreactions. First, biindoles are prepared from a palladium catalyzed cross coupling reaction. Second, a new palladium catalyzed benzannulation reaction employing biindolyl iodides and alkynes provides indolocarbazoles.
