Abstract

The enantioselective Pd(II)-catalyzed γ-C-H arylation of picolinamides with a chiral BINOL phosphate ligand was explored using density functional theory (DFT). Enantioselectivity arises from attractive aryl-aryl interactions between the pseudoequatorial phenyl substituent of the substrate and the chiral BINOL phosphate ligand.

摘要

采用密度泛函理论(DFT)研究了手性 BINOL 磷酸配体的对映选择性 Pd(II)-催化吡啶甲酰胺的 γ-C-H 芳基化反应。对映选择性来源于底物的假轴向苯基取代基与手性 BINOL 磷酸配体之间的芳基-芳基吸引力。
