via a gold(III) (C^N) complex-catalyzed three-component coupling reaction of aldehydes, amines and alkynes in water at 40 °C. Excellent diastereoselectivities (up to 99:1) have been achieved when chiral prolinol derivatives are employed as the amine component. Notably, the [Au(C^N)Cl2] complex (N^CH = 2-phenylpyridine) could be repeatedly used for 10 reaction cycles, leading to an overall turnover number
炔丙胺是通过金(III)(C ^ N)络合物催化醛,胺和炔烃在40°C的水中的三组分偶联反应以高收率合成的。当使用手性脯氨醇衍生物作为胺组分时,已经获得了极好的非对映选择性(高达99:1)。值得注意的是,[Au(C ^ N)Cl 2 ]络合物(N ^ CH = 2-苯基吡啶)可以重复使用10个反应周期,因此总周转数为812。
