A method for catalytic asymmetric alkylation of conjugated dienyl amides has been developed and it allows efficient and high‐yielding transformations of a wide range of polyconjugated amides into the corresponding chiral products. Smooth addition of organomagnesium reagents to relatively unreactive dienyl amides with excellent 1,6‐ and 1,4‐selectivities, as well as enantioselectivites above 90 %, is
已开发出一种共轭二烯基酰胺催化不对称烷基化的方法,该方法可以将各种范围的聚共轭酰胺高效高效地转化为相应的手性产物。由于路易斯酸和手性铜基催化剂的互补作用,可以将有机镁试剂平稳地添加到具有极好的1,6和1,4,4选择性以及相对于90%以上的对映体的相对无反应性的二烯基酰胺中。
