Thiazolidinones contain an active methylene group at 5-position. These methylene groups readily react with aromatic aldehydes to form benzylidene derivatives of the thiazolidinones. These benzylidene derivatives possess unsaturated carbonyl group which are further allowed to react with urea to form different pyrimidine rings after cyclisation.</p> https://journalofchemistry.org/paper/730/ Synthesis of Some Thiazolidino pyrimidines and Their Related Compounds
