摘要介绍了一种用光催化氧化还原法制备四氢呋喃和四氢吡喃的新方法。苯硫基辅助基团的引入允许底物容易被氧化以形成阳离子中间体，用于顺序的分子内环化。该方法反应条件温和，操作简便。
Abstract A new approach to the preparation of tetrahydrofurans and tetrahydropyrans through a photoredox catalytic process is described. The introduction of a phenylsulfanyl auxiliary group permits the substrates to be readily oxidized to form cationic intermediates for sequential intramolecular cyclization. The method features mild reaction conditions and operational simplicity.
