An operationally simple and efficient protocol for the construction of dihydrofuran derivatives has been accomplished via a sequential addition of N-chlorosuccinimide and a base to 2-amino-4H-pyran derivatives in alcohol medium. The one-pot protocol proceeding via tandem oxidative difunctionalization and ring contraction provides an entirely new strategy for the construction of the dihydrofuran skeleton.
通过在醇介质中依次添加N-氯代琥珀酰亚胺和碱,实现了一种操作简便且高效的构建二氢呋喃衍生物的协议。这一单锅法协议通过串联氧化双功能化和环收缩反应,为二氢呋喃骨架的构建提供了一种全新的策略。
