A novel dual gold/photoredox-catalyzed bis-arylative cyclization of chiral homopropargyl sulfonamides with diazonium salts has been developed, allowing the facile synthesis of various enantioenriched 2,3-dihydropyrroles in generally moderate to good yields with excellent enantioselectivities under very mild conditions without using any strong oxidants. The reaction is proposed to undergo an Au/Au redox cycle promoted by visible-light photoredox catalysis.
已开发出一种新型的手性高炔丙基磺酰胺与重氮盐的双金/光氧化还原催化双芳基化环化反应，该反应能在非常温和的条件下，不使用任何强氧化剂，以一般中等至良好的产率和优异的对映选择性，便捷地合成各种对映体富集的2,3-二氢吡咯。该反应被认为是通过可见光光氧化还原催化促进的金/金氧化还原循环进行的。
