A series of biologically active disubstituted benzofuran derivatives (3a–
d) have been designed and synthesized via C-H bond activation reaction. The
chemical structures of all final compounds were confirmed by spectroscopic
methods. In vitro anti acetylcholinesterase (AChE) activities of these novel
compounds were evaluated and showed low to moderate results. Among them,
compounds 3d moderately inhibited AChE activities with 68.12 % values
