[Omim]Cl/FeCl3-catalyzed cross-dehydrogenative-coupling of 1,4-benzoxazinones with various indoles

Metal‐Catalyzed Oxidative C−H Bond Functionalization of 1,4‐Benzoxazinones

“…A plausible mechanism for this reaction is shown in Figure 4 Ionic-liquid mediated, Fe-catalyzed oxidative cross-dehydrogenative coupling reaction of 1,4-benzoxazinones with substituted indoles under mild and eco-friendly conditions at ambient temperature was given by Sharifi and co-workers in 2020. [10] Where [Omim]Cl/FeCl 3 ) acts as both solvent and catalyst. After optimization, the reaction gave, 93 % isolated yield of the desired product (Scheme 6; 3 fa) by reacting 1,4benzoxazinone (1 f) and 1H-indole derivative (2 f) in the presence of 1.0 equiv.…”
