Abstract

Acyclic amino acids are one of the most ideal chiral scaffolds for the construction of organocatalysts. The development of acyclic amino acid based bifunctional chiral tertiary amines and their powerful catalytic abilities have been demonstrated in many asymmetric reactions. In this account, we summarize asymmetric transformations promoted by bifunctional chiral tertiary amines according to reaction patterns. Moreover, asymmetric reactions mediated by acyclic amino acid derived quaternary ammoniums as phase-transfer catalysts, and acyclic amino acid derived iminophosphoranes as bifunctional superbases are discussed.
