已开发出第一个银促进的 α-异氰基乙酸酯与作为芳香族迈克尔受体的 [3+4] 环加成反应,提供苯并[ d ][1,3] 二氮杂酮的途径。机理研究表明,这种脱芳环加成反应涉及“氧迁移”重排过程。此外,苯并[ d ][1,3]二氮杂酮在催化条件下也能有效获得。在温和的反应条件下,广泛的官能团具有良好的耐受性。

Silver-promoted dearomative [3+4] cycloaddition of anthranils with α-isocyanoacetates: access to benzodiazepines
anthranils as aromatic Michael accepters, offering access to benzo[d][1,3]diazepinones, has been developed. Mechanisticstudies revealed that an “oxygen migration” rearrangement process was involved in this dearomative cycloaddition reaction. Additionally, benzo[d][1,3]diazepinones were obtained efficiently as well undercatalyticconditions. Broad functional groups were well tolerated under mild reaction
