method using thiosemicarbazide, substituted phenacyl bromides, or substituted 3-(2-
bromoacetyl) coumarins, 1-Boc-3-cyano-4-pyrrolidone, or 1-Boc-3-cyano-4-piperidone. All
synthesized compounds' structures were confirmed by spectral (1H-and 13C-NMR, FTIR,
Mass) and analytical data. The target compounds were screened for their in vitro anticancer
activity. The results found that the compound 8a and 8b has shown significant …
