Saturated heterocycles are prevalent motifs in organic synthesis but their synthesis still presents persistent challenges. Now, a hypervalent iodine(III)-mediated selective intramolecular C(sp3)–H functionalization, facilitated by hexafluoroisopropanol, is reported, which via single-electron transfer provides access to pyrrolidines, piperidines and O-heterocycles in the presence or absence of light.
