Several sulfenamide derivatives were designed as possible acetylcholinesterase (AChE) inhibitors. New sulfenamides were synthesized and proved to be stable under the physiological conditions used in the enzymatic assays. N‐benzyl‐2‐benzoxazolylsulfenamide (8) and N‐benzyl‐2‐benzimidazolylsulfenamide (9) revealed anti‐AChE activity with IC50 values of 0.6 and 0.8 μM, respectively, values of the same
