An efficient one‐pot synthesis of indenes from simple starting materials is presented. This process involves a dual C–C bond formation by intermolecular Heck coupling followed by acid‐mediated intramolecular cyclodehydration. In addition, the regioselective synthesis of benzyl styrenes through in‐situ reduction of Heck products (ketones) followed by acid‐mediated dehydration is presented.
提出了一种由简单的起始原料有效地一键合成茚的方法。此过程涉及通过分子间的Heck偶联形成双重C–C键,然后进行酸介导的分子内环脱水。此外,还介绍了通过原位还原Heck产物(酮)然后进行酸介导的脱水来进行苄基苯乙烯的区域选择性合成。
