to employ the aminocatalyst as the sole chiral reagent. While the aminocatalyst dictates the enantioselectivity, diastereoselectivity is governed by the nature of an achiral, monodentate phosphine ligand on palladium.
通过使用协同的氨基和钯催化,公开了一种烯丙基烷基化反应,其中所有四种立体异构体都可以作为主要产物获得。重要的是,这种立体发散已被开发为使用氨基催化剂作为唯一的手性试剂。虽然氨基催化剂决定了对映选择性,但非对映选择性取决于钯上非手性单齿膦配体的性质。
