We developed Hg(OTf)2-catalyzed Friedel–Crafts-like cycloisomerization of 7-arylhepta-1,3-dienes to give propenyl-substituted tetrahydronaphthalenes in excellent catalytic turnover under very mild conditions. 1,3-Dienyl sulfonamides and 1,3-dienyl alcohols were also efficiently cyclized to afford heterocyclic compounds.
我们开发了 Hg(OTf)2 催化的 7-芳基庚-1,3-二烯类 Friedel-Crafts 环异构化反应,在非常温和的条件下以极佳的催化周转率得到
丙烯基取代的四氢
萘。1,3-二烯基磺酰胺和 1,3-二烯基醇也能高效地环化生成
杂环化合物。
