An unconventional Ugi : A catalytic asymmetric Ugi‐type reaction can be realized by use of N ′‐alkylbenzohydrazide, instead of a conventional amine, in the presence of an axially chiral dicarboxylic acid. The reaction proceeds through a key acyclic azomethine imine intermediate, which has recently emerged as a promising electrophile in asymmetric catalysis.
