demonstrated a metal-free transformation of cyclopropane carbaldehydes to oxybis(2-aryltetrahydrofuran) derivatives via a domino Cloke-Wilson rearrangement-hydration-dimerization sequence. Commercially inexpensive p-toluene sulfonic acid (PTSA) was used as a Brønsted acid catalyst, and reactions were conducted in an open-flask. Detection of reaction intermediates were carried to get an insight into the
在这项工作中,我们已经证明了通过多米诺克Cloke-Wilson重排-水合-二聚序列将环丙烷甲醛无金属转化为双(2-芳基四氢呋喃)衍生物。商业上便宜的对甲苯磺酸(PTSA)被用作布朗斯台德酸催化剂,并且反应在开瓶中进行。进行反应中间体的检测以深入了解反应途径。
