Abstract

AbstractAn unprecedented series of 2‐imino‐1,3‐thiazolidin‐4‐ones were designed by straightforward and dynamic technique via one‐pot three‐component reaction of isothiocyanatobenzene, primary amines, ethyl bromoacetate and/or phenacylbromide. Furthermore, we found that the reaction between 2‐imino‐1,3‐thiazolidin‐4‐one and arylidenemalononitrile using of C2H5ONa as catalyst gave the corresponding 3‐(2‐phenylethyl)‐5‐(4‐arylidene)‐2‐(phenyl imino)‐1,3‐thia‐zolidin‐4‐one instead of 5‐amino‐7‐aryl‐3‐(2‐phenylethyl)‐2‐(phenylimino)‐3,7‐dihydro‐2H‐6‐carbonitrile. The identical molecules were designed through other routes via the reaction of 2‐imino‐1,3‐thiazolidin‐4‐one with the corresponding aryl carbaldehyde.
