two-step synthesis of structurally diverse 3-aminoindazoles from readily available starting materials was developed. This sequence includes a one-pot synthesis of aminohydrazones through chemoselective Tf2O-mediated activation of tertiary amides and subsequent addition of nucleophilic hydrazides. These precursors then participate in an intramolecularligand-free Pd-catalyzed C–H aminationreaction. The
