Heteroatom is not needed: Access to dibenzo[e,h][1,4]diazecin-9-ones from dibenzo[b,e]azepin-6-one via the hydrated imidazoline ring expansion (HIRE) approach
5,11-Dihydro-6H-dibenzo[b,e]azepin-6-ones were for the first time expanded into 5,7,8,14-tetrahydrodibenzo[e,h][1,4]diazecin-9(6H)-ones via the so-called “hydrated imidazoline ring expansion” (HIRE).
5,11-Dihydro-6 H - dibenzo[ b,e ]azepin-6-ones 首次扩展为 5,7,8,14-tetrahydrodibenzo[ e,h ][1,4]diazecin-9( 6 H )-one 通过所谓的“水合咪唑啉环扩展”(HIRE)。
