The first selective PdII‐catalysed γ‐C(sp3)−H and γ‐C(sp2)−H arylation of free amino esters using a commercially available catalytic transient directing group. A variety of free amino esters, including α‐amino esters and β‐amino esters, amino monoesters and amino bis‐esters, are shown to react with a diverse range of simple aryl and heteroaryl iodide reagents.
首次使用选择性Pd II催化的游离氨基酯的γ-C(sp 3)-H和γ-C(sp 2)-H芳基化反应,使用市售的催化瞬态导向基团。各种游离的氨基酯,包括α-氨基酯和β-氨基酯,氨基单酯和氨基双酯,都可以与多种简单的碘化芳基和杂芳基试剂反应。
