Shao, Rui; Zhao, Haixia; Ding, Shumin; Li, Lianjie; Chen, Chen; Wang, Jian; Shang, Yongjia published an article in 2022, the title of the article was Silver-promoted dearomative [3+4] cycloaddition of anthranils with α-isocyanoacetates: access to benzodiazepines.SDS of cas: 2567-29-5 And the article contains the following content:
The first example of silver-promoted [3+4] cycloaddition of α-isocyanoacetates with anthranils as aromatic Michael accepters, offering access to benzo[d][1,3]diazepinones. Mechanistic studies revealed that an “oxygen migration” rearrangement process was involved in this dearomative cycloaddition reaction. Addnl., benzo[d][1,3]diazepinones were obtained efficiently as well under catalytic conditions. Broad functional groups were well tolerated under mild reaction conditions. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).SDS of cas: 2567-29-5
The Article related to anthranil isocyanoacetate silver promoter dearomative cycloaddition, dihydrobenzodiazepinone carboxylate preparation, Heterocyclic Compounds (More Than One Hetero Atom): Diazepines and other aspects.SDS of cas: 2567-29-5
