Catalytic Reductive Synthesis and Direct Derivatization of Unprotected Aminoindoles, Aminopyrroles, and Iminoindolines: A titanium(III)‐catalyzed radical cyclization to unprotected 3‐aminoindoles, 3‐aminopyrroles, or 3‐iminoindolines is reported. The reaction is non‐hazardous, scalable, and allows facile isolation of the of the free products by extraction.
