Asymmetric Intramolecular α‐Arylation of Polar Amino Acids Bearing β‐Leaving Groups

Angewandte Chemie International Edition, Accepted Article.
The α‐arylation of amino acids may be achieved by intramolecular nucleophilic aromatic substitution (SNAr) reactions of amino‐acid derived enolates, but for amino acids bearing β‐leaving groups, such reactions are complicated by competing E1cb elimination of the β‐substituent.
