Synthesis of some novel imidazolidine derivatives and their metal complexes with biological and antitumor activity

Abstract

Abstract 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.
