Site-Selective γ-C(sp3 )-H and γ-C(sp2 )-H Arylation of Free Amino Esters Promoted by a Catalytic Transient Directing Group.

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.
