A one-pot oxidative decarboxylation–Friedel-Crafts reaction of acyclic α-amino acid derivatives activated by the combination of iodobenzene diacetate/iodine and iron dust

An efficient one-pot oxidative decarboxylation-Friedel-Crafts reaction of acyclic alpha-amino acid derivatives with electron-rich aromatic compounds is reported. The reaction is activated by the combination of iodobenzene diacetate, iodine and iron dust, resulting in a mild and simple reaction system. The use of iron avoids the oxidation of aromatic compounds, and in situ generation of Fe(III) salts to promote the Friedel-Crafts reaction avoids the use of the highly hygroscopic FeCl(3).
