有机小分子催化剂由于易于合成，对环境友好，以及适用条件温和而成为不对称催化领域的研究热点之一.其中，手性亲核有机小分子催化剂是研究较多的一类，近年来取得了不错的研究进展，但是仍然存在催化活性较低和反应类型较窄等问题.因此开发新型高效亲核有机小分子催化剂具有较大的研究意义.2010年以来，本课题组设计并合成了一系列手性吡咯烷并咪唑催化剂，并将其成功应用于不对称Steglich重排、不对称Black重

手性稠环吲哚骨架广泛存在于天然产物及药物分子中,尤其是手性[a]-并环吲哚因其广谱的生物活性而引起了化学家们的广泛关注,1而吲哚N1位的直接官能团化是构建该类骨架最高效和符合原子经济性的方法之一,我们设想利用吲哚N1位的亲核性,设计开发一类结构新颖的吲哚类1,3-偶极体,通过其参与不对称环加成反应高效构建手性[a]-并环吲哚骨架.基于以上想法,我们将吲哚骨架与炔丙醇模块进行巧妙融合,设计合成乙炔基
