Application of 21778-81-4. 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 Rapid and selective access to three distinct sets of indole-based heterocycles from a single set of Ugi-adducts under microwave heating. Author is Zhang, Lei; Zhao, Fei; Zheng, Mingyue; Zhai, Yun; Liu, Hong.
Three distinct sets of indole-based heterocycles, e.g. I, II and III, were rapidly and selectively synthesized from the same set of Ugi-adducts, e.g. IV, under microwave heating in a reaction-condition-controlled manner. Notably, an unprecedented metal-free intramol. sp3-hybridized C-H arylation using only cesium carbonate was discovered.
After consulting a lot of data, we found that this compound(21778-81-4)Application of 21778-81-4 can be used in many types of reactions. And in most cases, this compound has more advantages.
