Abstract:

Pyrazole derivatives have attracted much attention over the past two decades in pesticide chemistry due to their diverse biological activities. Some of them have been used as herbicides, insecticides, fungicides and acaricides. Herein, we report the synthesis and the fungicidal and antiviral activity of novel series of 1 -substituted-3-methyl-5-benzylamino (alkylthio, or alkylsulfonyl)-1 H-pyrazole-4-carboxylic esters.
