Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Organic & Biomolecular Chemistry called Pd-catalyzed cascade allylic alkylation and dearomatization reactions of indoles with vinyloxirane, Author is Gao, Run-Duo; Xu, Qing-Long; Dai, Li-Xin; You, Shu-Li, which mentions a compound: 21778-81-4, SMILESS is O=CC(N1)=CC2=C1C=CC(OC)=C2, Molecular C10H9NO2, Electric Literature of C10H9NO2.
A palladium-catalyzed cascade allylic alkylation reaction of di-Me malonate tethered indoles with vinyloxirane was developed through intramol. nucleophilic ring-opening of vinyloxirane followed by subsequent intramol. Friedel-Crafts type allylic alkylation or allylic dearomatization. This protocol provided an efficient method to synthesize structurally diverse tetrahydrocarbolines e.g., I, and spiroindolenine derivatives e.g., II, under mild conditions.
From this literature《Pd-catalyzed cascade allylic alkylation and dearomatization reactions of indoles with vinyloxirane》,we know some information about this compound(21778-81-4)Electric Literature of C10H9NO2, but this is not all information, there are many literatures related to this compound(21778-81-4).
