Novel strategy for the preparation of 3-perfluoroalkylated-2H-indazole derivatives
Tetrahedron Letters, 2018Abstract A simple and novel methodology for the synthesis of 3-perfluoroalkylated-2H-indazole derivatives has been elaborated. The perfluoroalkylation of readily available 2-nitrobenzaldimines bearing electron donating groups was performed using the Ruppert-Prakash reagent and its analogues to afford α-difluoromethylated, α-trifluoromethylated and α ...

A regioselective synthesis of 2,3-disubstituted tetrahydro-2H-indazols, mediated by alpha-zirconium sulfophenylphosphonate-methanephosphonate, was reported. Docking studies into the catalytic site of COX-2 were used to identify potential anti-inflammatory lead compounds.

Mechanochemical synthesis and optical properties of solvatochromic 2H-indazole-3,5-diones
Dyes and PigmentsMechanochemical synthesis of 4-hydroxyazobenzene-2-carboxylic acids and their cyclization to highly-functionalized chromophores, 2-aryl-4-(arylamino)-2H-indazole-3,5-diones, is reported. Mechanism of the cyclization is suggested and supported by DFT calculations.
