Developing an efficient and highly enantioselective protocol to access homopropargyl amines is of high interest to the synthetic community and also remains a formidable challenge for organic chemists. Here, we present integrated Rh2(OAc)4- and BINOL-derived chiral phosphoric acid cooperatively catalyzed three-component reactions of alkynyldiazoacetates, imines with various nucleophiles including alcohols
开发一种有效且高度对映体选择性的方案以获取高炔丙基胺对合成界非常感兴趣,并且对于有机化学家来说仍然是一个艰巨的挑战。在这里,我们介绍了集成的Rh 2(OAc)4-和BINOL衍生的手性磷酸协同催化的炔基重氮乙酸酯,亚胺与各种亲核试剂(包括醇,吲哚和N,N-二取代苯胺)的三组分反应,从而提供了相应的高炔丙基胺包含两个邻近的手性中心,收率令人满意,具有非对映选择性和对映选择性高。
