Abstract

Some new pyrazole heterocycles such as dipyrazolyl ketones (3-8), pyrazolylindazolyl ketone, pyrazolopyrimidines (11-21) and bis pyrazolopyrimidines (18,22 and 23) have been synthesized starting from 5-amino-1-phenylpyrazole-4-carbohydrazide (2).Molluscicide activity of some new isolated pyrazole heterocycles has been reported.
