and enantioselectivity in the palladium‐catalyzed asymmetric allylic amination of racemic Morita–Baylis–Hillman adducts with aromatic amines. The methodology provides a facile and efficient synthesis of precursors for optically active β‐lactam derivatives, including the cholesterol drug Ezetimibe.
显示主链:双(膦)配体1的螺骨架主链在外消旋的Morita-Baylis-Hillman加合物与芳族胺的钯催化的不对称烯丙基胺化反应中产生了良好的区域和对映选择性。该方法为光学活性β-内酰胺衍生物(包括胆固醇药物依泽替米贝)的前体提供了便捷,高效的合成方法。
