Synthesis and biological activity of pyrazolothienotetrahydroisoquinoline and [1,2,4]triazolo[3,4-a]thienotetrahydroisoquinoline derivatives

1-Hydrazino-3-thioxo-5,6,7,8-tetrahydroisoquinoline-4-carbonitrile (3) was subjected to react with bifunctional compounds namely: acetylacetone, ethyl cyanoacetate, ethyl benzoylactate, diethylmalonate and ethyl acetoacetate to produce pyrazololthienotetr
