Abstract

A series of novel bis-thiazolidine derivatives with pyrrole ring was designed and synthesized. N-phenyl succinimide on haloformylation with Vilsmeier-Haack reagent (DMF/POCl3) furnished halovinyl aldehyde which on condensation with l-cysteine afforded the target compounds in catalytic amount of piperdine. The synthesized compounds were characterised by spectral analysis. Biological screening shows some of the synthesized compounds exhibit good anti-microbial activity.

Keywords: Bis-thiazolidine, halovinyl aldehydes, di-halo formy lation, DMF/POCl3.
