Abstract

Synthesis of 3‐(3‐nitrophenacyl)thiazolidine‐2,4‐dione 2g and 3‐(substituted phenacyl)‐5‐[3′‐(4__H__‐4‐oxo‐1‐benzopyran‐2‐yl)‐benzylidene]‐2,4‐thiazolidinediones 4a–g are reported in this paper. These compounds 4a–g were prepared from 3′‐flavone carboxaldehyde and 3‐substituted phenacyl‐2,4‐thiazolidinediones using Knoevenagel reaction. The structures of all compounds were confirmed by IR, ^1^H‐NMR, mass spectral data, and elemental analyses. The molecules 4a–g were evaluated for in‐vitro antimicrobial activity against Staphylococcus aureus, Candida albicans, Candida krusei, Candida glabrata, and Candida parapsilosis. Compounds 4c and 4f showed better inhibitory activity when compared to fluconazole against Candida krusei and Candida glabrata.
