A facile and efficient approach for the synthesis of spirooxindoles has been developed via the coupling of spirocyclic C, C-palladacycles with CH2Br2. The key spirocyclic palladacycles are generated catalytically via intramolecular remote C–H activation. A range of spirooxindoles can be synthesized in good to excellent yields from readily available starting materials.
通过螺环C,C-palladacycles与CH2Br2的耦合,已开发出一种简便高效的合成螺硫辛多酯的方法。关键的螺环戊四环是通过分子内远程C–H活化催化生成的。可以从容易获得的起始原料中以良好至极好的产率合成一系列螺硫醇。
