n of alkenes with anilines has been developed for the atom-economical synthesis of 2-substituted propanamides bearing an α-stereocenter. A novel phosphoramidite ligand L16 was discovered which exhibited very high reactivity and selectivity in the reaction. This asymmetric Markovnikov hydroaminocarbonylation employs readily available starting materials and tolerates a wide range of functional groups
已经开发了钯催化的烯烃与苯胺的不对称马尔科夫尼科夫氢氨基羰基化反应,用于原子经济合成带有 α-立体中心的 2-取代丙酰胺。发现了一种新的亚磷酰胺配体 L16,它在反应中表现出非常高的反应性和选择性。这种不对称 Markovnikov 氢氨基羰基化使用容易获得的起始材料并耐受范围广泛的官能团,从而为在环境条件下区域选择性和对映选择性合成 2-取代丙酰胺提供了一种简便而直接的方法。机理研究表明,该反应通过钯氢化物途径进行。
