 Title    Related Compounds from l,4-Bis(ethoxycarbonyl)-2,5-diamino-l,4-cyclohexadiene  
 Abstract    Interaction of o-phenylenediamine with l,4-Bis-(ethoxycarbonyl)-2,5-diamino-l,4-cyclo-hexadiene (1) gave 2, which cyclised to the hexahydrobenzodiazepinone (3). On the other hand, interaction of 1 with o-aminophenol, gave compound 4 which on treatment with polyphosphoric acid gave the tetrahydrobis-benzooxazepinone (11). Treatment of 1 with phenylisothiocyanate and formamide afforded the dithiopyrimidoquinazolinone (8) and the tetrahydropyrimidoquinazolinone (9), while the interaction of 1 with benzenesulphonyl-chloride gave dibenzenesulphonamido-cyclohexadiene dicarboxylate (10). The structure of these compounds was established by chemical and spectroscopic methods.
