In summary, we have developed a simple and efficient one-pot, two-step procedure to synthesize the carbazole and dibenzofuran ring systems and related compounds. This process involves the reaction of o-iodoanilines or o-iodophenols with silylaryl triflates in the presence of CsF to afford the N- or O-arylated products, which are subsequently cyclized to carbazoles and dibenzofurans in situ using a Pd catalyst. The starting materials are commercially available or can be easily prepared using known chemistry. The yields are good to excellent. Several new and multisubstituted carbazoles and dibenzofurans have been synthesized using this chemistry. By using this methodology, the carbazole alkaloid mukonine has been synthesized in 76% overall yield in three steps from a commercially available starting material.
Although arynes have historically received much attention from organic chemists, their use as reagents in synthetic organic chemistry has been somewhat limited due to the harsh reaction conditions needed to generate arynes and the often uncontrolled reactivity exhibited by these species. Recently, silylaryl triflate 1a has been employed in the presence of CsF to generate benzyne under very mild reaction conditions. The resulting aryne readily undergoes a variety of electrophilic and nucleophilic reactions, several novel insertion reactions, and even Pd-catalyzed annulation reactions. We have reported that silylaryl triflates can react with a variety of nucleophiles, such as anilines and phenols to generate very high yields of the corresponding N- and O-arylated products and even more important is the fact that halides, such as iodides and bromides, are readily tolerated by the reaction conditions. We have taken advantage of this methodology to develop a simple, economical, and efficient one-pot, two-step procedure to synthesize the carbazole and dibenzofuran ring systems in good to excellent yields through the cross-coupling of o-iodoanilines or o-iodophenols with silylaryl triflates in the presence of CsF, followed by palladium-catalyzed intramolecular cyclization. Herein, we wish to provide a full account of the scope and limitations of this chemistry. We have also applied this chemistry to the high yield three-step synthesis of an interesting carbazole alkaloid, mukonine.
