Safety of 5-Methoxy-1H-indole-2-carbaldehyde. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 5-Methoxy-1H-indole-2-carbaldehyde, is researched, Molecular C10H9NO2, CAS is 21778-81-4, about Enantioselective Synthesis of Polycyclic Nitrogen Heterocycles by Rh-Catalyzed Alkene Hydroacylation: Constructing Six-Membered Rings in the Absence of Chelation Assistance. Author is Du, Xiang-Wei; Ghosh, Avipsa; Stanley, Levi M..
In the presence of [Rh(1,5-COD)Cl]2, AgBF4, and (R)-2,2′-bis[di(4-methylphenylphenyl)phosphino]-1,1′-binaphthyl [(R)-Tol-BINAP], alkenylindolecarboxaldehydes such as I (R = Me, Et, BuCH2CH2, PhCH2, Ph, 4-MeC6H4, 4-ClC6H4, EtO2C; R1 = H, Et) and N-alkenylpyrrolecarboxaldehydes underwent enantioselective hydroacylation to give tetrahydropyridoindolones such as II (R = Me, Et, BuCH2CH2, PhCH2, Ph, 4-MeC6H4, 4-ClC6H4, EtO2C; R1 = H, Et) or indolizinones in 23-98% yields and in 92-99% ee; the enantioselective cyclizations did not require chelation or other functional groups to facilitate cyclization. The structure of II (R = Me; R1 = Br) was determined by X-ray crystallog.
There is still a lot of research devoted to this compound(SMILES：O=CC(N1)=CC2=C1C=CC(OC)=C2)Safety of 5-Methoxy-1H-indole-2-carbaldehyde, and with the development of science, more effects of this compound(21778-81-4) can be discovered.
