An Improved Synthesis of Disubstituted 2H-indazoles using Microwaves

Letters in Organic Chemistry, 2023
Abstract: Microwaves have been used to produce a practical, high-yielding, and scalable synthesis method for producing disubstituted 2H-indazoles. With this technique, a large class of 2H-indazoles can be effectively produced from substituted 2-bromobenzaldehyde, aromatic amine and NaN3 using [Cu(phen)(PPh3)2]NO3 as catalysts.

2H-indazoles from 2-aminobenzophenones

Chemistry of Heterocyclic Compounds, 2008
2H-Indazoles have proved difficult to prepare and, hence, have not been studied extensively. Only one general method is known for the preparation of such compounds, which involves the acid-catalyzed rearrangement of 2-arylazophenylcyclopropanes [1]. We are the first to show that 4,5-ethylenedioxy-2-phenylazobenzophenones 1 and 2, which may be readily ...

Electrochemically mediated trifluoromethylation of 2H-indazole derivatives using CF3SO2Na

Tetrahedron Letters, 2021
Abstract An environmentally friendly method of electrochemical mediated regioselective C-3 trifluoromethylation of 2H-indazole by employing CF3SO2Na as the CF3 source was described. This reaction tolerated various functional groups and provided C H trifluoromethylated products in moderate to good yields under transition metal-free and oxidant-free ...

Recent synthetic approaches to 1H- and 2H-indazoles (microreview)

Chemistry of Heterocyclic Compounds, 2020
The work summarizes latest strategies for the synthesis of 1H- and 2H-indazoles published during the last five years. The strategies include transition metal catalyzed reactions, reductive cyclization reactions, and synthesis of 2H-indazoles via consecutive formation of C–N and N–N bonds without catalyst and solvent from 2-azidobenzaldehydes and amines.
