背景:Strecker反应是首次报道的用于制备α-氨基腈的多组分反应。α-氨基腈是各种氨基酸,1,2-二嗪,杂环和生物活性化合物(如Saframycin A和Ecteinascidin 746)的重要中间体。采用Strecker方法使用MCR制备α-氨基腈,由于原子经济性而避免了多步操作,因此吸引了许多研究小组的注意。合成并遵循绿色化学原理。 方法:在纯净条件下,在一锅中以Cu(BF4)2.xH2O为催化剂,通过Strecker反应,通过TMSCN处理醛,胺,合成了A-氨基腈。已经用不同的伯胺和仲胺研究了各种芳族和脂族醛。 结果:通过在各种溶剂下选择模型反应来优化反应条件,并在纯净条件下发现良好的收率。此外,还研究了各种催化量的Cu(BF4)2.xH2O,发现3摩尔%的产率更高。已经用醛和胺的不同底物研究了该反应。通过比较其光谱数据(1 H NMR,13 C NMR,IR和MS)和物理
