Tetrazole Placeholder-Directed Strategy: Precise Synthesis of Tri(tetrazolyl)-Functionalized Pyrazole
{{output}}
We report a concise synthesis of the fully tetrazole-substituted pyrazole 3,4,5-tris(1H-tetrazol-5-yl)-1H-pyrazole (TYX-39). The key intermediate, 3,5-dicarbonitrile-4-(1H-tetrazol-5-yl)-1H-pyrazole (2), was prepared by a piperidine-catalyzed one-pot condensat... ...
