A nickel-catalyzed regiosepecific C2- versus C3-oxidative cross-coupling reaction of indoles with 1,4-dioxane and other inactive C(sp3)–H bonds is described. The divergent synthesis of C(sp3)–C(sp2) bonds was achieved in satisfactory yields with di-tert-butyl peroxide (DTBP) as the oxidant, which provides an efficient strategy for the selective construction of cyclic ethers containing heteroaromatic
