We report a novel visible-light-driven photoredox-catalyzed cascade reaction involving Conia-ene-type cyclization and Smiles rearrangement initiated from alkyne-tethered α-sulfonyl esters. This methodology not only facilitates the rapid synthesis of a broad spectrum of highly substituted methylenecarbocycles but also introduces a new mechanistic pathway with aryl group migration, surpassing the conventional 1,5-hydrogen shift typically observed in Conia-ene reactions.
我们报道了一种新型的可见光驱动的光氧化还原催化级联反应，该反应涉及由炔基连接的α-磺酰基酯引发的Conia-烯型环化和Smiles重排。这种方法不仅有助于快速合成多种高度取代的亚甲基碳环，而且引入了一种新的带有芳基迁移的机理途径，超越了Conia-烯反应中通常观察到的传统1,5-氢迁移。
