<br/><br/> The present work is undertaken to synthesize a variety of multi-linked heterocycles containing thiazolidin-4-one miety which would be expected to have potent biological activities. N,N'-diarylethylene-bis-thiourea derivatives were utilized as key starting material for the synthesis of several new 1,2-bis-(2-(phenylimino)-1,3-thiazolidin-3-yl)ethane derivatives
