COA of Formula: C10H9NO2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5-Methoxy-1H-indole-2-carbaldehyde, is researched, Molecular C10H9NO2, CAS is 21778-81-4, about Convenient synthesis of tetrahydro-γ-carbolines and tetrahydroquinolines through a chemo- and regioselectivity switch by a Bronsted acid catalyzed, one-pot, multicomponent reaction. Author is Cheng, Hong-Gang; Chen, Cai-Bao; Tan, Fen; Chang, Ning-Jie; Chen, Jia-Rong; Xiao, Wen-Jing.
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.
There is still a lot of research devoted to this compound(SMILES：O=CC(N1)=CC2=C1C=CC(OC)=C2)COA of Formula: C10H9NO2, and with the development of science, more effects of this compound(21778-81-4) can be discovered.
