A new strategy for the synthesis of N-alkoxycarbonyl aryl α-imino esters in the presence of dirhodium tetraacetate [Rh2(OAc)4] is reported to produce the desired compounds in high yield (up to 96%) under mild reaction conditions. The application of the synthetic method is demonstrated in enantioselective reduction and Friedel–Crafts reaction of indoles to afford the corresponding chiral arylglycines
