Abstract

Starting from 2-hydroxybenzyl alcohol, a series of 2-arylbenzofurans have been synthesized and evaluated as acetylcholinesterase inhibitors at 23 μM by using modified colorimetric Ellman's method. The reaction sequence was completed in four steps. All of the fourteen synthesized products were obtained in excellent yields without the need to tedious work-up step. In the last step, different derivatives were obtained by the substitution of bromine with five and six-membered cyclic and acyclic amines. Among the synthesized compounds, the best activity was observed in 1-(4-(Benzofuran-2-yl) benzyl)piperidine 5c with 74 activity compared to donepezil as a reference drug. © 2016 Bentham Science Publishers.
