✦ Synopsis

A novel heterocycle-heterocycle inter-conversion is reported. It enables direct and efficient syntheses of either polysubstituted 2-arylimino-1,3-oxazolidine or 2-arylimino-1,3-thiazolidine hydrochlorides by a one-pot treatment of 4-amino-2phenyl-2-oxazolines with arylisocyanates or arylisothiocyanates, respectively, followed by addition of hydrochloric acid.

## Abstract Synthesis and characterization of bis[2‐(arylimino)‐1,3‐thiazolidin‐4‐ones] are described. The one‐pot, pseudo‐five‐component reaction of an aliphatic diamine, isothiocyanatobenzene, and dialkyl but‐2‐ynedioate at room temperature in anhydrous CH~2~Cl~2~ gives the title compound in rela
