-
Paragraph 0126, (2013/08/15)
A method of synthesizing Pyrazoles by means of the oxidative conversion of Enamines with suitable N-containing carboxylic acid derivatives in the presence of copper ions and 2-picolinic acid derivatives is provided.

An efficient Cu-catalyzed formation of tetra-substituted pyrazoles is reported. In this atom economic process, readily available enamines and nitriles are reacted by C-C and N-N bond formation. Oxygen has been successfully used as the oxidant, which has i
