In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Extending the versatility of the Hemetsberger-Knittel indole synthesis through microwave and flow chemistry, published in 2013-03-15, which mentions a compound: 67929-86-6, Name is Methyl 5-methoxyindole-2-carboxylate, Molecular C11H11NO3, Computed Properties of C11H11NO3.
Microwave, flow and combination methodologies were applied to the synthesis of a number of substituted indoles. Based on the Hemetsberger-Knittel (HK) process, modifications allow formation of products rapidly and in high yield. Adapting the methodol. allows formation of 2-unsubstituted indoles and derivatives, and a route to analogs of the antitumor agent PLX-4032 is demonstrated. The utility of the HK substrates is further demonstrated through bioconjugation and subsequent ring closure and via Huisgen type [3+2] cycloaddition chem., allowing formation of peptide adducts which can be subsequently labeled with fluorine tags.
