- Synthesis, structure elucidation, and biological evaluation of some fused and/or pendant thiophene, pyrazole, imidazole, thiazole, triazole, triazine, and coumarin systems based on cyanoacetic 2-[(benzoylamino)thioxomethyl] hydrazide
-
Aiming to produce cyclized systems with potential bioactivity, a variety of fused and/or pendant thiophene, pyrazole, imidazole, thiazole, triazole, triazine, and coumarin systems were synthesized based on a cyanoacetic 2-[(benzoylamino)thi- oxomethyl] hy
