  functionalization with a collection of O, N, and S nucleophiles, using oxygen as the terminal oxidant. Preliminary mechanistic observations and the first synthesis of the cytotoxic natural product strongylophorine‐26 is presented.

  理想情况下，杂原子取代的对苯醌的制备是通过直接添加亲核试剂，然后进行原位再氧化来完成的。尽管是一种引人注目的策略，但对p-醌部分的反应性不容易驯服，也没有广泛适用的杂原子官能化方法。这里示出的是，钴（OAC）2和Mn（OAc）3 ⋅2ħ 2 ö充当强大催化剂氧化p为O，N的集合-quinone官能化，和S的亲核试剂，使用氧作为氧化剂终端。介绍了初步的机械观察结果和细胞毒性天然产物Strongylophorine-26的首次合成。

  Cycloalkenobezofurans 5a-d were prepared in one-pot reaction from methoxyhydroquinone, 2,6- and 2,3-dialkoxyhydroquinone (1) with cycloalkenediol (2). Reaction between the isomeric 2,5-dialkoxyhydroquinones (9) with diol 2 led to the formation of monoalkoxybenzofurans 5d-g with the loss of an alkoxy group.
