  非对称羰基化反应中模块化膦-亚磷酰胺配体的合成与应用：结构-选择性关系

  摘要：

  通过手性BINOL（1,1'-bi-2-萘酚）或NOBIN（2-amino-2'-hydroxy-1,1'-binaphthyl）设计并合成了一系列杂化膦-亚磷酰胺配体。他们在苯乙烯衍生物（支链/线性比高达56.6，ee高达99％），乙酸乙烯酯衍生物（高达ee高达98％）和烯丙基氰化物（高达RH）的Rh催化的不对称加氢甲酰化反应中获得了很高的区域和对映选择性。96％ee）。配体结构的系统变化表明，亚铁酰胺部分上的空间因子决定了配体的性能。随着障碍的增加，支链/线性比率上升，而ee苯乙烯的加氢甲酰化过程中的分子量值下降。但是，N取代基对选择性的影响不大。
