Diazotization of N,N'-dialkyl-N-(o-aminophenyl) ureas 7, 13 and 17 gave 3,5-dimethyl-3H-1,2,3,5-benzotetrazepin-4(5H)-one 8, 3-methyl-6,7-dihydro-1,2,3,5-tetrazepinoquinolin-4(3H)-one 14 and 3-methyl-6,7-dihydrooxazino-1,2,3,5-benzotetrazepin-4-one 19.The structures of these bi- and tri-cyclic systems were confirmed by 1H, 13C and 15N NMR data.X-Ray diffraction of compound 14 shows that the tetrazepinone ring is nonplanar.
