A general and simple protocol for the arylation of Baylis-Hillman adducts derived from nitroolefins leading to novel classes of (E)-2-nitro-1,3-diarylprop-1-enes and 1-[(E)-2-nitro-3-arylallyl]naphthalenes via an intermolecular Friedel-Crafts reaction have been achieved. Further application of these compounds has been demonstrated for the synthesis of pyrrolidines and 3-spiropyrrolidines which are integral components of many natural products and bioactive molecules.
通过分子间弗里德尔-卡夫斯反应,实现了从硝基烯烃衍生出的 Baylis-Hillman 加合物的芳基化的一般和简单方案,从而得到了新型 (E)-2-nitro-1,3-diarylprop-1-enes 和 1-[(E)-2-nitro-3-芳基烯丙基]萘。这些化合物在合成吡咯烷和 3-巯基吡咯烷方面的进一步应用已得到证实,而吡咯烷和 3-巯基吡咯烷是许多天然产品和生物活性分子的组成部分。
