frequently used chemical reaction in the pharmaceutical field. Developing protocols for the nucleophilic substitution of (indol-2-yl)methyl electrophiles is important for functionalizing indoles. There are few studies on the nucleophilic substitution at the 2′-position of the electrophiles without an electron-withdrawing group at the 1-position or substituents at the 2′- and 3-positions, where the existing

An efficient regioselective sp3 C–H azidation is developed using CuBr as the catalyst and Zhdankin azidoiodinane as the “N3” source. Under simple and mild reaction conditions, the azido group could be successfully incorporated into the sp3 C–H alkyl substituents of indoles and tetrahydrocarbazoles.
使用CuBr作为催化剂,Zhdankin azidoiodinane作为“ N 3 ”源,开发了一种高效的区域选择性sp 3 C-H叠氮化反应。在简单温和的反应条件下,叠氮基可以成功地掺入吲哚和四氢咔唑的sp 3 C–H烷基取代基中。
