An unprecedented protocol for a Rh(III)-catalyzed [3 + 2] annulation from simple and readily available enaminones and iodonium ylides has been developed. The novel strategy allows for access to a new class of structurally diverse tetrahydro-indolones with high efficiency and a broad substrate scope. In addition, this transformation represents the first example of the selective Rh(III)-catalyzed alkenyl C-H bond functionalization and annulation of enaminones. Finally, the potential applications of this protocol are demonstrated through gram-scale reaction and late-stage modification.
已经开发出一种前所未有的用于铑（III）催化的由简单易得的烯胺酮和碘鎓叶立德进行[3+2]环化反应的方案。这种新策略能够高效地合成一类结构多样的新型四氢吲哚酮，且底物范围广泛。此外，这种转化代表了铑（III）催化的烯基C-H键官能团化以及烯胺酮环化反应的首个选择性实例。最后，通过克级规模反应和后期修饰展示了该方案的潜在应用。
