In a one pot procedure, a series of novel methylene-bis-thiazolidinone derivatives 5 and 6 was prepared by condensation of 5-(3-formyl-4-methoxybenzyl)-2-methoxybenzaldehyde 3 with mercapto acids and primary aromatic amines 4 in presence of ZnCl2 under both microwave irradiation and conventional heating conditions. High yields are achieved even on a gram scale, while reaction times are considerably
