The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5-Methoxy-1H-indole-2-carbaldehyde(SMILESS: O=CC(N1)=CC2=C1C=CC(OC)=C2,cas:21778-81-4) is researched.Computed Properties of C7H13BrO2. The article 《Copper-Catalyzed Annulation of 2-Formylazoles with o-Aminoiodoarenes》 in relation to this compound, is published in Journal of Organic Chemistry. Let’s take a look at the latest research on this compound (cas:21778-81-4).
In the presence of catalytic CuI and sparteine, 2-formylpyrroles can be annulated with o-aminoiodoarenes to give substituted pyrrolo[1,2-a]quinoxalines and related heterocycles. The reaction also works for annulation of 2-formylindoles, 2-formylimidazole, 2-formylbenzimidazole, and a 3-formylpyrazole.
From this literature《Copper-Catalyzed Annulation of 2-Formylazoles with o-Aminoiodoarenes》,we know some information about this compound(21778-81-4)Synthetic Route of C10H9NO2, but this is not all information, there are many literatures related to this compound(21778-81-4).
