Abstract: | The condensation of 1,5-diaminoimidazoles with ethyl aceto-acetate gives two types of compounds: imidazo1,5-b]-1,2,4-triazepinones and imidazo4,5-b]pyridinones. The structure of these compounds is demonstrated by rmn and mass spectroscopy. The formation of imidazo4,5-b]pyridinones from imidazo1,5-b]-triazepinones through a new transposition is also shown. |
