  苯并香豆素是在天然产物和合成分子中广泛发现的重要结构基序。合成苯并香豆素及其衍生物的传统方法需要多个步骤，通常需要进行分子内酯形成反应以使内酯环成为最后一步。另一种主要方法涉及过渡金属催化的偶联或碳氢键活化反应，该反应从底物中预先存在的芳基骨架开始。在这里，我们报告了绿色和快速获得苯并香豆素及其衍生物的新策略。我们的方法使用容易获得的不饱和醛和香豆素作为底物，使用空气作为绿色氧化剂。整个反应通过正式的[4 + 2]过程进行，以构建新的苯环，从而基本上在单个步骤中得到苯并香豆素。没有使用金属催化剂。不涉及有毒或昂贵的试剂。我们的新方法的强大功能在大麻素（一种具有生物活性的天然产物）的简明正式全合成中得到了进一步证明。
