Abstract

Nowadays considerable attention is given to the development of new methods for the preparation of pyrazole derivatives since the presence of pyrazole ring in organic molecules gives rise to versatile physiological activity of many compounds of both synthetic and natural origin [1]. 3-Alkenylpyrazoles and bipyrazoles attract specific interest [1–6]. For example, 3- (2-methylprop-1-en-1-yl)-1H-pyrazole was found to enhance soporific effect of ...
