the synthesis of 3-amino-1,4-diynes. Although metal-catalyzed A3-coupling reactions have been extensively used to synthesize various propargylamines, the A3-coupling for the synthesis of 3-amino-1,4-diynes has been rarely reported. In this study, various symmetrical 3-amino-1,4-diynes were synthesized by the sequential Cu-catalyzed dealkynylation of propargyl aldehydes followed by A3-coupling. Unsymmetrical
研究了铜催化的 A3(胺、醛和炔)偶联反应以合成 3-氨基-1,4-二炔。尽管金属催化的 A3-偶联反应已被广泛用于合成各种炔丙胺,但很少报道用于合成 3-氨基-1,4-二炔的 A3-偶联反应。在这项研究中,通过连续铜催化炔丙醛脱炔化和 A3 偶联合成了各种对称的 3-氨基-1,4-二炔。不对称的 3-氨基-1,4-二炔也通过铜催化的 A3 偶联以 49-85% 的产率合成。
