Abstract:Chiral allenes are important structural scaffolds found in many natural products
and drugs, and in addition, they also serve as building blocks for many organic transformations.
The conventional methods for preparing chiral allenes rely on the resolution of
racemic allenes and the chirality transfer between non-racemic propargylic derivatives and
nucleophilic reagents. In recent years, the synthesis of chiral allenes by asymmetric catalysis
has been achieved fruitful results. Among them, enantioselective synthesis of chiral
allenes with chiral organic catalysts is particularly prominent. In this paper, the research
progress of enantioselective synthesis of chiral allenes catalyzed by chiral organic catalysts
in recent years is reviewed, including various reaction systems and synthesis applications.
