An efficient approach was developed for the α-arylation of imino amides with arylboronic acids. Different substrates were examined for this arylation reaction. For the α-arylation of N-phenylimino amide, due to the electron-withdrawing properties of the phenyl group, the tautomerization between the amide and the iminol is more difficult. Thus, low reaction rate and low conversion were observed. This
开发了一种有效的方法,用于亚氨基酰胺与芳基硼酸的 α-芳基化。针对该芳基化反应检查了不同的底物。对于N-苯基亚氨基酰胺的α-芳基化,由于苯基的吸电子特性,酰胺与亚胺醇之间的互变异构化更加困难。因此,观察到低反应速率和低转化率。这种现象支持我们之前提出的α-氨基酸衍生物芳基化机制。同时,该方法为α-功能化甘氨酸衍生物的合成提供了一种替代方法。
