A Friedel–Crafts alkylation reaction of thiophenes with glyoxylate imine was developed to give α-aminoesters. In the presence of FeCl3·6H2O as the catalyst, various α-aminoesters were prepared with moderate to high yields (up to 95%) except for some special substrates.
开发了噻吩与乙醛酸亚胺的弗瑞德-克福特(Friedel-Crafts)烷基化反应,得到α-氨基酯。在FeCl 3 ·6H 2 O作为催化剂的存在下,除某些特殊底物外,制备了各种中等至高产率(高达95%)的α-氨基酯。
