We report the chiral diene ligated rhodium-catalyzed dynamic kinetic asymmetric transformation (DYKAT) of racemic secondary allylic trichloroacetimidates with a variety of N-methyl anilines, providing allylic N-methyl arylamines in high yields, regioselectivity, and enantiomeric excess. The rhodium-catalyzed DYKAT method addresses limitations previously associated with this particular class of aromatic
我们报告了手性二烯与各种N-甲基苯胺的外消旋仲烯丙基三氯乙酰亚胺的铑催化的动态动力学动力学不对称转化(DYKAT),提供了高产率,区域选择性和对映体过量的烯丙基N-甲基芳基胺。铑催化的DYKAT方法解决了以前与这类特殊的芳香族氮亲核试剂有关的局限性。
