Attempted cycloaddition of benzimidazole-2-thiol with arylidenemalononitriles 1 was unsuccessful. 2-Cyanomethyl-1,3-benzothiazole 6 condensed with certain aromatic aldehydes to produce 7, cycloaddition of which with cyanoacethydrazide 3 yielded B. Structure of the newly synthesized compounds was substantiated by spectroscopic data and/or unambiguous synthesis. Representative compounds were screened for antimicrobial activity.
