Quality Control of (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole, is researched, Molecular C38H24F4O4P2, CAS is 503538-69-0, about Copper(I)-catalyzed dearomative (3 + 2) cycloaddition of 3-nitroindoles with propargylic nucleophiles: a straightforward access to cyclopenta[b]indolines. Author is Ling, Johanne; Mara, David; Roure, Baptiste; Laugeois, Maxime; Vitale, Maxime R..
The copper(I)-catalyzed dearomatization of 3-nitroindoles with propargylic nucleophiles is described. In mild reaction conditions, this original dearomative (3 + 2) cycloaddition process gives access to a wide variety of cyclopenta[b]indolines in good to excellent yields, with high functional group tolerance. Furthermore, an enantioselective version of this reaction is reachable by employing chiral phosphorous ligands. A mechanism proposal is given, based on kinetic studies.
