The study of Friedel-Crafts alkylation reaction of thiophenes with glyoxylate imine catalyzed by Fe(III): An easy access to α-aminoesters

Huang, Zhong,Zhang, Jingchang,Wang, Nai-Xing

, p. 1788 - 1791 (2011/04/15)

A Friedel-Crafts alkylation reaction of thiophenes with glyoxylate imine was developed to give α-aminoesters. In the presence of FeCl 3·6H2O as the catalyst, various α-aminoesters were prepared with moderate to high yields (up to 95%
