摘要

Asymmetric cycloisomerization catalyzed by transition metals, which possesses highly catalytic activity and good selectivity, is a potential protocol to fulfill the goal of "atom economy". In recent years, impressive achievements have been made in this area. It becomes one of the most efficient methods to synthesize enantiomeric pure carbon- or heterocyclic compounds. This paper summarized the development of transition metal catalyzed asymmetric cycloisomerization in recent twenty years and briefly reviewed its applications in total synthesis of natural products.
