Synthesis of 3-Alkyl-5-Benzylidene-2,4-Thiazolidinedione Under Microwave Irradiation

Microwave irradiation of aromatic aldehyde and 2,4-thiazolidinedione provides a fast and high-yield access to 5-benzylidene-2,4-thiazolidinedione. Seven 3-alkyl-5-benzylidene-2,4-thiazolidinedione compounds were produced with high yield by reacting 5-benzylidene-2,4-thiazolidinedione with different alkylating agents under microwave irradiation.
