The work summarizes newest methods for the synthesis of 1H- and 2H-indazoles released over the last 5 years. The techniques incorporate transition steel catalyzed reactions, reductive cyclization reactions, and synthesis of 2H-indazoles via consecutive development of C–N and N–N bonds without having catalyst and solvent from 2-azidobenzaldehydes and amines.
