Diversityorientedsynthesis of natural 2‐arylbenzofuran, moracin F (1) has been carried out from the commercially available starting materials using Sonogashira coupling, Suzuki coupling, neutral Al2O3 mediated cyclization, and intramolecular Wittig reaction as key steps.
使用Sonogashira偶联,Suzuki偶联,中性Al 2 O 3介导的环化和分子内Wittig反应作为关键步骤,已经从市售的起始原料中进行了面向天然的2-芳基苯并呋喃,草精F(1)的多样性导向合成。

An efficient chlorination of indoles and electron‐rich arenes with chlorine anion as nucleophile is described. With the use of ethyl phenyl sulfoxide as the promoter, the reaction went smoothly under metal‐free and mild conditions. Various indoles and electron‐rich arenes are converted into the corresponding chlorinated compounds in moderate to excellent yields. A plausible interrupted Pummerer reaction
