A Raney nickel-catalyzed desulfurization is the last step in the Gassman method for synthesizing these compounds, and they can also be synthesized by an intramolecular Wittig reaction in a variant of the Madelung synthesis.
A Raney nickel-catalyzed desulfurization is the last step in the Gassman method for synthesizing these compounds, and they can also be synthesized by an intramolecular Wittig reaction in a variant of the Madelung synthesis. The presence of the simplest of these compounds can be detected by the Kovacs reagent, and another of them was formed via the first reported intramolecular Heck reaction. They are synthesized from ketones in a [3,3]-sigmatropic rearrangement named after Fischer. For 10 points, name these heterocyclic aromatic molecules that contain a benzene ring fused to a pyrrole, whose namesake functional group is found on the side chain of tryptophan.
