The function summarizes most recent tactics for your synthesis of 1H- and 2H-indazoles revealed in the previous five years. The procedures involve transition metal catalyzed reactions, reductive cyclization reactions, and synthesis of 2H-indazoles via consecutive formation of C–N and N–N bonds without the need of catalyst and solvent from 2-azidobenzaldehydes https://tycoonchemstore.com/product-category/indazole-based/
