temperature have been developed using an in situ generated N-nitroso group as a transient oxidizing directinggroup. Due to mild reaction conditions, this method enabled synthesis of a broad range of N-alkyl indoles, including even two indole-based medicinal compounds. Our work disclosed the feasibility of the transient oxidizing directinggroup strategy in C–H functionalization reactions, which possesses

have developed a strategy of Rh(III)-catalyzed C—H activation of N-nitrosoanilines and iodonium ylides to construct novel tetralydrocarbzol-4-one scaffolds, which provided valuable templates for sequentialC—Hfunctionalization such as alkylation, alkenylation, amidation and (hetero)arylation at C5-position of tetralydrocarbzol-4-one with different coupling partners.
