The synthesis of N-unprotected indoles has been realized via Rh(III)-catalyzed C–Hactivation/annulation of imidamides with α-diazo β-ketoesters. The reaction occurs with the release of an amide coproduct, which originates from both the imidamide and the diazo as a result of C═N cleavage of the imidamide and C–C(acyl) cleavage of the diazo. A rhodacyclic intermediate has been isolated and a plausible

Indoles are an important structural motif that is commonly found in biologically active molecules. In this work, conditions for divergentcouplings between imidamides and acceptor–acceptor diazo compounds were developed that afforded NH indoles and 3H‐indoles under ruthenium catalysis. The coupling of α‐diazoketoesters afforded NH indoles by cleavage of the C(N2)−C(acyl) bond whereas α‐diazomalonates
