  precursors 10 is presented. The putative oxonium ion intermediate 17 formed by an intramolecular hydroxyl cyclization followed by dehydration is reduced in situ by an added dihydroquinone source. Good to excellent yields of cyclized products are realized in all cases except for highly electron deficient systems, and these suffer reduction prior to oxonium ion formation. All products are monomeric and

  提出了一种由2-（2'-羟乙基）醌前体10酸催化构造二氢苯并呋喃杂环（14）的方法。通过分子内羟基环化然后脱水形成的假定的氧鎓离子中间体17通过添加的二氢醌源原位还原。除高度缺乏电子的系统外，在所有情况下均实现了良好至优异的环化产物收率，并且这些化合物在形成氧离子之前遭受还原。除10克外，所有产物均为单体，均来自两电子转移，可得到二聚二氢苯并呋喃。环化或还原产物的量取决于醌底物与二氢醌添加剂之间的HOMO / LUMO间隙，
