An efficient gold‐catalyzed synthesis of pyrazolo[1,5‐ a ]pyridines have been developed from pyrazolo substituted propargyl alcohols via 6‐ endo‐dig cyclization. In this intramolecular cyclization reaction a new C−N bond was formed regioselectively and good to excellent yields of pyrazolo[1,5‐ a ]pyridines were obtained in one‐pot.
