  8‐Membered cyclic ethers are found in a wide range of natural products; however, they are challenging synthetic targets due to enthalpic and entropic barriers. The gold(I)‐catalyzed intramolecular dehydrative alkoxylation of ω‐hydroxy allylic alcohols was explored to stereoselectively construct α,α′‐cis‐oxocenes and further applied in a formal synthesis of (+)‐laurencin. The gold(I)‐catalyzed intramolecular

  8-元环醚存在于多种天然产物中。然而，由于焓和熵的屏障，它们对合成目标具有挑战性。探索了金（I）催化的ω-羟基烯丙醇的分子内脱水烷氧基化反应以立体选择性地构建α，α'-顺式茂新烯烃，并进一步用于（+）-月桂素的形式合成中。金（I）催化的分子内脱水烷氧基化反应可能是合成包含高功能化8元环醚的分子构件和天然产物的另一种方法。
