A series of novel 5-ethylidene-thiazolidine-2,4-diones derivatives were synthesized by the knoevenagel condensation of aromatic ketone and N-substituted thiazolidinedione-2,4-diones. Use of KAl(SO4)2•12(H2O) i.e. Alum for the reaction makes this synthesis facile because of the some advantageous impacts viz. nontoxicity, efficient catalytic ability and lower cost of alum. Substitution of arylidene moiety at the position 5 on the thiazolidine-2,4-diones nucleus was carried out in this facile approach. Synthesized derivatives were characterized using various analytical tools and antimicrobial evaluation thereof was performed against Gram-positive, Gram negative bacteria and a fungal strain. All synthesized compounds showed moderate to very good activity against the microorganisms that they were tested for.
