A COMPARATIVE STUDY BETWEEN IMIDAZOLIDINEIMINOTHIONES AND4-THIOXOIMIDAZOLIDINE-2,5-DIONES TOWARDS SOME NUCLEOPHILIC AND BINUCLEOPHILIC REAGENTS: SYNTHESIS OF SOME NEW IMIDAZO(DIIMINES, DIHYDRAZONES, QUINOXALINES & AZINE) AND DIIMIDAZOLIDINONE
摘要:
Reactions of 5-imino-4-thioxoimidazolidine (II) and 4-thioxoimidazolidine-2,5-diones (III) with amines, hydrazine hydrate, hydrazine derivatives, o-phenylenediamines and cupper turnings were investigated.

structures (3-aminopyrroline-2-thiones and 3-iminopyrrolidine-2-thiones). The latter was reacted with chloroacetic acid, ethylchloroacetate, chloroacetamide and 2,3-dichloro-l,4-naphthoquinone to give the corresponding pyrrolothiazines derivatives. On using phenylisocyanate or p-chlorobenzoyl chloride, the corresponding pyrrolothiazole derivatives could be isolated. Replacement of chalcones by maleimides furnished
