PYRAZOLES are aromatic 5-diazoles with a variety of chemical and biological characteristics, but they also have a rich and interesting history. The reaction of 1,3-dicarbonyl compounds quickly proved to be useful for the synthesis of other heterocycles, and has been used to prepare numerous compounds, which were widely used in the following decades. The particular limitation of this method in the synthesis of pyrazole is the control of the regiochemistry of n-substituted pyrazole. The method relies on Regioselectivity N functionalization of N unsubstituted pyrazoles or Regioselectivity condensation of asymmetric hydrazine with 1,3 dicarbonyl equivalent. These strategies can often lead to regional isomer mixtures, especially when highly complex pyrazole is required.
