Halogenated imidazo(pyrazine,[1,4]diazocine and quinoxaline), 9,10‐anthraquinone‐ [6,7‐e], phenanthroline[5,6‐e] {imidazo[4,5‐b]pyrazine}, and naphtho[1,8‐ef]imidazo[4,5‐b][1,4] diazipen were obtained through interaction of imidazolidineiminothiones with the corresponding diamino compounds. Imidazo[4,5‐e] triazine and pyrrolo[2,3‐d]imidazole were prepared when the iminothiones were reacted with thiocarbohydrazide and with ethylphenyl acetate, separately. Some of the synthesized compounds exhibited better biological and antitumor activities. © 2006 Wiley Periodicals, Inc.

New types of halogenated, alkylated and (bis)cyanothio-formamides were prepared and reacted with iso(thio)cyanates, aldehydes and dibenzylideneacetone to produce (bis)imidazolidineimino(di)thiones and (oxazolidine and bispyrrolidine)iminothiones, respectively. Imidazolidineiminothiones were reacted with H 2 S/TEA to give thiohydantoin which reacted with p-chlorobenzaldehyde to achieve the corresponding thienoimidazole derivative. Most of the synthesized products exhibited antibacterial, antifungal and antitumor activities.
