3-amino-7, 8-dihydro-1-phenylimidazo[1, 5-b]cinnolin-9(6H)-ones, cyclohexane-1, 3-diones, 1, 2-diamino-4-phenylimidazole, dimethyl formamide dimethyl acetal, 2-(phenylaminomethylidene)cyclohexane-1, triethyl orthoformate, three-component condensationAbstract
The reaction of 1,2-diamino-4-phenylimidazole with 5,5-R,R1-cyclohexane-1,3-diones and with the dimethyl formamide dimethyl acetal or triethyl orthoformate gives 7,7-R,R1-3-amino-1-phenyl-7,8-di-hydroimidazo[1,5-b]cinnolin-9(6H)-ones in good yield. These products may also be obtained from 1,2‑diamino-4-phenylimidazole and 5,5-R,R1-(phenylaminomethylidene)cyclohexane-1,3-diones.
