A Convenient Method for Stereoselective Synthesis of β-Aminoesters. Iron(II) Iodide or Trityl Hexachloroantimonate as an Effective Catalyst in the Reaction of Ketene Silyl Acetals with Imines

Mukaiyama, Teruaki,Akamatsu, Hidekazu,Han, Jeong Sik

, p. 889 - 892 (2007/10/02)

In the presence of a catalytic amount of iron(II) iodide or trityl hexachloroantimonate, ketene silyl acetals smoothly react with imines to afford the corresponding β-aminoesters in good yields with anti-selectivities.
