A novel synthesis of substituted pyrrolo[2,3-e]indoles and thieno[2,3-e]indoles is described. This new approach uses 1,3-cyclohexanedione as the starting material. Diketone intermediates are obtained in four steps from the aforementioned ketone. Using these intermediates, the title compounds are synthesized efficiently.

A highly efficient iron-catalyzed approach to polysubstituted pyrroles has been developed through the [4C+1N] cyclization of 4-acetylenic ketones with primary amines, leading to the synthesis of a variety of tetra- and fully-substituted pyrroles as well as fused pyrrole derivatives in good to excellent yields.
