Palladium-catalyzed amination proved to be a valuable strategy for the selective introduction of aromatic and heteroaromatic amines, including aminopyridines and aminodiazines, on dichloropyridines. The use of mild amination conditions resulted in maximum selectivity and excellent base sensitive functional group tolerance.
事实证明,
钯催化的胺化反应是在二
氯吡啶上选择性引入芳族和杂芳族胺(包括
氨基吡啶和
氨基二嗪)的有价值的策略。使用温和的胺化条件可实现最大的选择性和出色的碱敏感性官能团耐受性。
