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 Convenient synthesis of tetrahydro-γ-carbolines and tetrahydroquinolines through a chemo- and regioselectivity switch by a Bronsted acid catalyzed, one-pot, multicomponent reaction, published in 2010-09-30, which mentions a compound: 21778-81-4, Name is 5-Methoxy-1H-indole-2-carbaldehyde, Molecular C10H9NO2, Application In Synthesis of 5-Methoxy-1H-indole-2-carbaldehyde.
An efficient, one-pot, multicomponent reaction of aldehydes, p-methoxyaniline, and 2-vinylindoles was developed. This approach provides a practical approach to synthetically and biol. significant tetrahydro-γ-carboline and tetrahydroquinoline derivatives in good yields through a chemo- and regioselectivity switch, which can be tuned by simply changing the substituent on the indole component under identical reaction conditions.
In some applications, this compound(21778-81-4)Application In Synthesis of 5-Methoxy-1H-indole-2-carbaldehyde is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
