An efficient approach for the stereoselective synthesis of (E)-β-aminoacrylonitriles from 1,2,3-triazine is presented. The reactions employ Cu(OAc)2 to promote direct 1,2,3-triazine coupling with various secondary amines and subsequent aerobic oxidation without the participation of ligand, base or chemical oxidant additives. This user-friendly protocol has merits of substrate availability, easy operation
提出了一种从 1,2,3-三嗪立体选择性合成 ( E ) -β-氨基丙烯腈的有效方法。该反应使用 Cu(OAc) 2来促进 1,2,3-三嗪与各种仲胺的直接偶联和随后的有氧氧化,而无需配体、碱或化学氧化剂添加剂的参与。这种用户友好的协议具有底物可用性、操作简单和产品产率高的优点,具有优异的 ( E )- 立体选择性。
