Abstract

Palladium-catalyzed reductive N-heteroannulation of ortho-nitrostyrenes has become a synthetically useful method for the construction of indoles and indole-based heterocycles. Soderberg's elaboration of this methodology has been utilized in the synthesis of indoles and quinolines from a common precursor. The same protocol has also been employed in the synthesis of the indole alkaloid Salviadione. A systematic investigation of chemoselectivity in Kosugi-Migita-Stille coupling reactions provided the basis for the synthesis of isomeric pyrroloindoles through palladium-catalyzed reductive double N-heteroannulation of dinitro-dialkenyl benzenes.
