A selective, metal-free synthesis of boron-functionalized indenes and benzofulvenes via BCl3-mediated cyclization of o-alkynylstyrenes is described. The method allows precise control over product formation by adjusting reaction conditions. These borylated products were utilized in diverse C–B bond derivatizations and in the total synthesis of Sulindac, a nonsteroidal anti-inflammatory drug, demonstrating
描述了通过 BCl 3介导的邻炔基苯乙烯环化选择性地无金属合成硼官能化茚和苯并富烯。该方法可以通过调节反应条件来精确控制产物的形成。这些硼化产物被用于各种 C-B 键衍生化和非甾体类抗炎药苏林酸的全合成,证明了所开发的合成应用方法的多功能性和实用性。
