highly regioselective functionalization of indole at the C-4 position by employing an aldehyde functional group as a directing group, and Ru as a catalyst, under mild reaction conditions (open flask) has been uncovered. This strategy to synthesize 4-substitutedindoles is important, as this class of privileged molecules serves as a precursor for ergotalkaloids and related heterocyclic compounds.
