Graphical Abstract
  • previously mentioned compounds were synthesized in order to evaluate their antiviral and cytotoxic activity. Moreover, antibacterial activity of some of these derivatives has also been studied. Some of the tested compounds have shown interesting results and a brief survey is given in the following section

Graphical Abstract
  • -alkynylthieno[2,3- d]pyrimidines were prepared via alkynylation of 4-chlorothieno[2,3-d]pyrimidines in good to excellent yields. Some of the compounds synthesized were tested for cytotoxic activity in vitro. Keywords: catalysis; C–C bond; copper; palladium; thieno[2,3-d]pyrimidine; Introduction Alkynyl
