One advantage of the Bartoli indole synthesis is the ability to produce indoles substituted on both the carbocyclic ring and the pyrrole ring, which is difficult to do with the Leimgruber-Batcho indole synthesis.
The Bartoli indole synthesis offers a distinct advantage over the Leimgruber-Batcho indole synthesis in that it allows for the creation of indoles with substituents on both the carbocyclic ring and the pyrrole ring, which is difficult to accomplish using the latter method.
