story? N‐Aryl amides are effective directing/activating groups for chlorosilane Lewis acids. This aspect has been exploited for the development of the first simple and general method for the highlyenantioselective Pictet–Spengler reaction of ketimines derived from α‐ketoamides leading to quaternary α‐aminoacid derivatives (see scheme).
