The reactivity of 7‐alkynycycloheptatrienes tethered to an aryl group under π‐acid catalysis has been studied. A variety of useful cyclic products were synthesized via Au(I)‐catalyzed skeletal reorganization, Cu(II)‐catalyzed hydroarylation, or Brønsted acid‐catalyzed tandem hydroarylation/Friedel‐Crafts reaction. We also report a rare type of skeletal reorganization involving the 1,3‐acetonide tether
研究了在π-酸催化下束缚在芳基上的7-炔基环庚烯的反应性。通过Au(I)催化的骨架重组,Cu(II)催化的氢芳基化或Brønsted酸催化的串联氢芳基化/ Friedel-Crafts反应合成了多种有用的环状产物。我们还报告了在一价阳离子Ga(I)+复合物存在下涉及1,3-丙酮化物系链的罕见类型的骨骼重组。
