Sonochemistry: A good, fast and clean method to promote the synthesis of 5-arylidene-2,4-thiazolidinediones
摘要:
The efficient synthesis of sixteen 5-arylidene-2,4-thiazolidinediones by aldol condensation reaction of 2,4-thiazolidinedione, mono- and di-substituted arenealdehydes and KOH using ultrasound irradiation is reported. The desired compounds were obtained in a few min (10-30 min) with moderate to good yields (25-81%). (C) 2014 Elsevier B.V. All rights reserved.
