Construction of 1,2-dihydroisoquinolines and 1-alkylidenyl-1,2,3,4-tetrahydroisoquinolines through cationic gold(I) complex catalyzed hydroamination of the corresponding alkynyl carbamates has been demonstrated. In the presence of EtOH, the reaction proceeded smoothly at room temperature with low catalyst loading (1-3 mol%).
1,2-二氢异喹啉和 1-亚烷基-1,2,3,4-四氢异喹啉通过阳离子金 (I) 络合物催化的相应炔基氨基甲酸酯的加氢胺化的构建已被证明。在 EtOH 存在下,反应在室温下顺利进行,催化剂负载量较低(1-3 mol%)。
