TLDR
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.Abstract:

Aldehydes vs Aldimines. Unprecedented Aldimine-Selective Nucleophilic Additions in the Coexistence of Aldehydes Using a Lanthanide Salt as a Lewis Acid Catalyst
Shū Kobayashi,Satoshi Nagayama +1 more
TL;DR: In this paper, preferential reactions of aldimines over aldehydes in nucleophilic additions using a lanthanide salt as a Lewis acid catalyst was described, and it is well-recognized that aldinines are less reactive than aldehides toward nucleophoric additions.
