Palladium-Catalyzed Oxidative Direct C3- and C7-Alkenylations of Indazoles: Application to the Synthesis of Gamendazole

, 2016
The first palladium-catalyzed oxidative alkenylation of (1H)- and (2H)-indazole derivatives with various olefins is described. The use of Pd­(OAc)2 as the catalyst and Ag2CO3 as the oxidant promoted the selective C3-monoalkenylation of (1H)-indazoles and

A simplified Cadogan’s approach to synthesis of new isoxazolyl indazoles

, 2008
1591-1596Isoxazolyl Schiff bases have been prepared from the corresponding amines by reaction with 2-nitrobenzaldehydes.These nitro compounds undergo de-oxygenative cyclization to give indazoles via nitrenes on heating with triethyl phosphite in ...

CuO nanoparticle catalysed synthesis of 2H-indazoles under ligand free conditions

, 2014
A CuO nano catalysed one-pot synthesis of 2H-indazoles has been devised from easily accessible starting materials viz. 2-bromobenzaldehydes, primary amines and sodium azide under ligand free conditions.
