Synthetic and Biological Studies on 4-Aryloxymethyl Coumarinyl Thiazolidinones

Abstract

A series of new thiazolidinonyl -4-aryloxymethylcoumarins ( 4a–h ) have been synthesized from 4-Bromomethylcoumarins ( 1a–b ) and 4-aryliminomethyl-phenols ( 2a–d ). Structures of all the new compounds are elucidated by elemental analyses, IR, ¹ H NMR, and mass spectral data. All these compounds have been subjected to in-vitro antimicrobial and in-vivo anti-inflammatory screening.

Keywords:

• Coumarins
