general method for preparation of benzothiazole derivatives including oxidative cyclization of the corresponding Schiff bases was reported. Herein, we have been synthesized a series of new acyclic‐substituted bis(2‐arylbenzothiazoles). Synthesis of analogs substituted in the benzothiazole ring was achieved via the direct condensation reaction of o‐aminothiophenol with some of dialdehyde compounds under

A synthesis of bis‐ and poly(benzimidazoles) as well as bis‐ and poly(benzothiazoles) was attempted using different protocols. The best results were obtained by employing the reaction of the appropriate bis‐ or poly(aldehydes) with o‐phenylenediamine or 2‐aminothiophenol, respectively, in ethanol at reflux in the presence of NaHSO3. The anticancer activities of the synthesized compounds were evaluated
