A cascade cyclization of para-quinamines and 2-furanylmethanol has been achieved, affording a series of functionalized hydrobenzo[c,d]indoles in moderate to good yields and excellent diastereoselectivities under mild conditions. This reaction was first initiated by the Mitsunobu reaction and then followed by the [4 + 2] Diels-Alder reaction to furnish the important indole-fused heterocyclic derivatives.
芳基取代的对醌亚胺与 2-呋喃甲醇发生级联环化反应,在温和条件下以中等至良好的收率和优异的非对映选择性得到一系列功能化的氢化苯并[c,d]吲哚。该反应首先由 Mitsunobu 反应引发,然后通过[4+2]Diels-Alder 反应得到重要的吲哚稠合杂环衍生物。
