摘要：

Activated enol ethers derived from methyl or ethyl acetoacetate/ cyanoacetates or nitriles and pentane-2,4-dione react with pentafluorophenylhydrazine through the primary amino-group to afford pyrazoles bearing a preferred 5-amino-over 5-methyl-or 5-hydroxy-substituent in the resulting 4-substituted pyrazoles.
