We synthesized cinnamoyl amide type chiral P,olefin ligand (S)-4. We successfully obtained separable diastereomers of 4d and demonstrated Pd-catalyzed asymmetric allylic substitution reactions of indoles using (S,aS)-4d as a chiral ligand with high enantioselectivities (up to 98% ee).
我们合成了肉桂酰胺型手性P,烯烃配体( S ) -4。我们成功地获得了4d的可分离非对映异构体,并证明了使用 ( S , aS ) -4d作为具有高对映选择性(高达 98% ee)的手性配体的Pd 催化的吲哚不对称烯丙基取代反应。
