Cp*Co(iii)-catalyzed [4+1] annulation of sulfoxonium ylides with anthranils has been developed for the synthesis of indole-indolone scaffolds. The dual functionality of anthranils was exploited, wherein the nitrogen has been used for C-H amination and the aldehyde group was utilized in the subsequent intramolecular aldol condensation to furnish the corresponding annulated products.
Cp*Co(iii)-催化的亚砜叶立德与邻氨基苯甲酸的[4+1]环化反应已被开发用于吲哚-茚满骨架的合成。邻氨基苯甲酸的双重功能被利用，其中氮用于 C-H 氨化，醛基用于随后的分子内醛缩合，以提供相应的环化产物。
