A low-temperature, protecting-group-free oxidation of 2-substituted anilines has been developed to generate an electrophilic N-aryl nitrenoid intermediate that can engage in C-NAr bond formation to construct functionalized N-heterocycles. The exposure of 2-substituted anilines to PIFA and trifluoroacetic acid or 10 mol percent Sc(OTf)3 triggers nitrenoid formation, followed by productive and selective C-NAr and C-C bond formation to yield spirocyclic- or bicyclic 3H-indoles or benzazepinones. Our experiments demonstrate the breadth of these oxidative processes, uncover underlying fundamental elements that control selectivity, and demonstrate how the distinct reactivity patterns embedded in N-aryl nitrenoid reactive intermediates can enable access to functionalized 3H-indoles or benzazepinones.
I(III)-catalyzed oxidative cyclization - Migration tandem reactions of unactivated anilines
Deng, Tianning,Shi, Emily,Thomas, Elana,Driver, Tom G.
supporting information, p. 9102 - 9106 (2020/11/13)
An I(III)-catalyzed oxidative cyclization-migration tandem reaction using Selectfluor as the oxidant was developed that converts unactivated anilines into 3H-indoles is reported herein. The reaction requires as little as 1 mol % of the iodocatalyst and is mild, tolerating pyridine and thiophene functional groups, and the dependence of the diastereoselectivity of the process on the identity of the iodoarene or iodoalkane precatalyst suggests that the catalyst is present for the stereochemical determining C-N bond forming step.

While several methods are available for the synthesis of a host of trifluoromethylated heterocycles, very few of them have been applied to access 4-trifluoromethylated 1,2,3-triazoles. We report herein a general methodology for the trifluoromethylation of 1-aryl-4-iodo-1, 2, 3-triazoles. Tetrabutylammonium iodide (TBAI) has been shown to provide enhanced conversion in these CuI-mediated reaction using methyl 2,2-difluoro-2-(fluorosulfonyl)acetate (MDFA). The method exhibited broad functional group tolerance and was applied to the synthesis of a library of 1-aryl-4-trifluoromethyl-1,2,3-triazoles on the multi-gram scale.
