Reaction Conditions:
with thiourea;urea at 110; for 0.116667 h;Neat (no solvent);Knoevenagel condensation;
Steps:
General procedure for the synthesis of 5-arylidenethiazolidine-2,4-diones and 5-arylidene-2-thioxothiazolidin-4-ones:
General procedure: A mixture of aldehyde (1 mmol), 2,4-thiazolidinediones/2-thioxothiazolidin-4-ones (1 mmol) using 10 mol % urea/thiourea as catalyst was condensed at 110 °C on oil bath under solvent-free reaction conditions. After completion of the reaction as indicated by TLC, the crude product was cooled, washed with water (10 mL), filtered and recrystallization from ethanol: DMF to afford 3a-ab.
