Ammoniomethyl trifluoroborates are very powerful reagents that can be used to access biologically relevant aryl‐ and heteroaryl‐methylamine motifs via Suzuki–Miyaura cross‐couplings. Until now, this method was limited to the production of tertiary and primary amines. The synthesis of a large array of secondary ammoniomethyltrifluoroborates has been achieved through a one step nucleophilic substitution
氨甲基三氟硼酸盐是非常强大的试剂,可用于通过 Suzuki-Miyaura 交叉偶联获得生物学相关的芳基和杂芳基甲胺基序。到目前为止,这种方法仅限于生产叔胺和伯胺。通过对溴甲基三氟硼酸钾的一步亲核取代反应,合成了大量仲氨甲基三氟硼酸盐。基于氨基联苯钯预催化剂的使用,设计了平滑的交叉偶联条件,以有效地将这些三氟硼酸盐与芳基溴化物偶联。该策略提供了一种访问生物学相关基序的新方法,并允许使用先前开发的方法访问所有三类氨甲基芳烃。
