An efficient synthesis of indazoles from readily accessible E/Z mixtures of o-haloaryl N-tosylhydrazones has been developed. The thermo-induced isomerization of N-tosylhydrazones is discussed. A series of valuable indazole derivatives are prepared in good yields, and the method has been successfully applied to the synthesis of the bioactive compounds, lonidamine, AF-2785, axitinib, YC-1 and YD-3.

This paper describes a Suzuki Type cross coupling reaction of 3- iodoindazoles with aryl and heteroaryl boronic acids as a general route to 3- arylindazoles. The coupling reaction is illustrated by the preparation of new aryl- or heteroarylindazoles 7. Scope and limitation of the method are outlined. The coupling reaction works best on a 1-substituted indazole nucleus. The usefulness of the reaction is illustrated by a short practical synthesis of YC-1, a pharmacological agent potentially useful for the treatment of cardiovascular diseases or erectile dysfunction.
