  A gold-catalyzed tandem annulation of propargylic alcohols and pyridylhomopropargylic alcohols is achieved, providing an atom-economical approach to a diverse set of polycyclic dihydrobenzofurans in good yields. The reaction proceeds via the 5-endo-dig cyclization/Meyer–Schuster rearrangement/Friedel–Crafts-type pathway. In this way, three C–C bonds and one C–O bond form to give a polycyclic skeleton

  实现了金催化的炔丙醇和吡啶基高丙基丙醇的串联环氧化，从而为高收率的多种多环二氢苯并呋喃提供了一种原子经济的方法。反应通过5 -endo-dig环化/ Meyer-Schuster重排/ Friedel-Crafts型途径进行。这样一来，三个碳原子键和一个碳原子键形成了一个一锅法的多环骨架。此外，这些产品还展现出独特的光学性能，从而揭示了其潜在的应用价值。
