The three-component couplings of α-oxyaldehydes, alkynes, and amines in water were investigated by using gold, silver and copper catalysts. Gold(I) was found to be the most effective catalyst in this reaction to afford propargylamines in good yields and moderate diastereoselectivities. On the other hand, silver catalysts show the best catalytic activities on non-coordinating α-alkyl-substituted aldehydes
通过使用金,银和铜催化剂研究了水中的α-氧化醛,炔烃和胺的三组分偶联。发现金(I)是该反应中以高收率和中等非对映选择性提供炔丙基胺的最有效催化剂。另一方面,银催化剂对非配位的α-烷基取代的醛显示出最佳的催化活性。
