A robust and scalable formal [4 + 3] annulation reaction for the synthesis of optically pure 1,4-benzodiazepinones and 1,4-benzoxazepinones has been established by a combined catalytic system consisting of a chiral NHC, a chiral Ir/phosphine-olefin complex, and an achiral urea, enabling the asymmetric synthesis of a selective inhibitor of mitochondrial F1F0 ATP hydrolase.
通过由手性 NHC、手性 Ir/膦-烯烃组成的组合催化系统,建立了用于合成光学纯 1,4-苯二氮杂酮和 1,4-苯并恶氮杂酮的稳健且可扩展的正式 [4 + 3] 环化反应复合物和非手性尿素,能够不对称合成线粒体 F 1 F 0 ATP水解酶的选择性抑制剂。
