Arylation of 3-oxo-2,3-dihydroindoles with aryllead triacetates was written by Merour, Jean Yves;Chichereau, Lucien;Finet, Jean Pierre. And the article was included in Tetrahedron Letters in 1992.Electric Literature of C10H9NO2 This article mentions the following:
Arylation of 2-alkoxycarbonyl-3-oxo-2,3-dihydroindoles I (R = H, Me, COMe; R1 = CO2Me, CO2Et; R2 = H) with aryllead (IV) triacetates II (R3 = H, OMe) leads selectively to 2-alkoxycarbonyl-2-aryl-3-oxo-2,3-dihydroindoles III. Direct selective C-arylation of 1-substituted-3-oxo-2,3-dihydroindoles I (R = COMe, SO2Ph; R1 = H, Me, Ph; R2 = H, Me, OMe) with II (R3 = OMe) affords the corresponding 1-substituted-2-aryl-3-oxo-2,3-dihydroindoles III. In the experiment, the researchers used many compounds, for example, 1-Acetylindolin-3-one (cas: 16800-68-3Electric Literature of C10H9NO2).
1-Acetylindolin-3-one (cas: 16800-68-3) belongs to indole derivatives. Indole, first isolated in 1866, and it is commonly synthesized from phenylhydrazine and pyruvic acid, although several other procedures have been discovered. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings.Electric Literature of C10H9NO2
