Herein, we describe an unprecedented cascade reaction to β-stereogenic γ-lactams involving Pd(II)-catalyzed enantioselective aliphatic methylene C(sp )-H alkenylation-aza-Wacker cyclization through syn-aminopalladation. Readily available 3,3'-substituted BINOLs are used as chiral ligands, providing the corresponding γ-lactams with broad scope and high enantioselectivities (up to 98 % ee).
在此,我们描述了一种前所未有的β-手性γ-内酰胺级联反应,涉及 Pd(II)催化的对映选择性脂肪族亚甲基 C(sp 3 )-H 烯丙基化-aza-Wacker 环化反应,通过顺式-氨钯化实现。可大量获得的 3,3'-取代的联萘酚被用作手性配体,为相应的γ-内酰胺提供了广泛的范围和高对映选择性(高达 98%ee)。
