Copper-Catalyzed Mild and Efficient
Entry to 1-Substituted Indazolones
摘要:
A variety of 1-alkyl- and aryl-substituted indazolones were synthesized easily starting from commercially available 2-halobenzoic acids and hydrazines via the copper-catalyzed intramolecular C-N bond formation of 2-halobenzohydrazides under mild conditions.
