3-Hydrazinylidene-2,3-dihydro1H,2-benzothiazole 1 was synthesized as reported before. Compound 1 was allowed to react with different electrophilic reagents (aldehyde-sugars, aldehydes, and anhydride).
Structures of all synthesized compounds were elucidated from (IR, Mass spectrum) and elemental analysis. Some of the resulting compounds were screened against selected microbes to test their antimicrobial activities.
