Bis(dibenzylideneacetone)palladium(0)/tert-Butyl Nitrite- Catalyzed Cyclization of o-Alkynylanilines with tert-Butyl Nitrite: Synthesis and Applications of Indazole 2-Oxides

An efficient method for the synthesis of 1-benzyl/arylindazole 2-oxides via a bis(dibenzylideneacetone)palladium(0) [Pd(dba)2]/tert-butyl nitrite (TBN)-catalyzed reaction of o-alkynylaniline derivatives with TBN is reported. The overall transfo

Copper(I) Oxide-Mediated Cyclization of o-Haloaryl N-Tosylhydrazones: Efficient Synthesis of Indazoles

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.
