A Ru(II)-catalyzed C–H bond activation/annulation of N-iminopyridinium ylides with sulfoxoniumylides has been developed for the synthesis of diverse functionalized isocoumarin derivatives. This method features broad substrate scope, high functional group tolerance, simple operation and silver salt-free conditions. Furthermore, the synthetic utility of this method is demonstrated by the alkenylation
已经开发了一种 Ru( II ) 催化的N-亚氨基吡啶叶立德与锍叶立德的 C-H 键活化/环化,用于合成各种官能化的异香豆素衍生物。该方法具有底物范围广、官能团耐受性高、操作简单、无银盐条件等特点。此外,该方法的合成效用通过产物的烯基化和生物活性 thunberginol A 的有效合成得到证明。

Page 5738. Entries 12–19 of Table 2 were inadvertently omitted. The corrected version of Table 2 follows: The reactions were performed in a sealed tube with 1 (0.5 mmol), CuI (0.05 mmol), 2-picolinic acid (0.1 mmol), and K2CO3 (1.0 mmol) in toluene (2 mL) at 110 °C under nitrogen. Isolated yield. This article has not yet been cited by other publications.
