Application In Synthesis of 5-Methoxy-1H-indole-2-carbaldehyde. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-Methoxy-1H-indole-2-carbaldehyde, is researched, Molecular C10H9NO2, CAS is 21778-81-4, about Synthesis of 9H-Pyrrolo[1,2-a]indole and 3H-Pyrrolizine Derivatives via a Phosphine-Catalyzed Umpolung Addition/Intramolecular Wittig Reaction. Author is Saleh, Nidal; Voituriez, Arnaud.
The first umpolung addition/intramol. Wittig reaction, catalytic in phosphine, is described. The in situ phosphine oxide reduction was accomplished by the use of silane and a catalytic amount of bis(4-nitrophenyl)phosphate. This catalytic protocol is applicable to the synthesis of a wide range of functionalized 9H-pyrrolo[1,2-a]indoles and pyrrolizines (18 examples, 70-98% yields).
Although many compounds look similar to this compound(21778-81-4)Application In Synthesis of 5-Methoxy-1H-indole-2-carbaldehyde, numerous studies have shown that this compound(SMILES:O=CC(N1)=CC2=C1C=CC(OC)=C2), has unique advantages.
