Asymmetric Catalysis for the Synthesis of Spirocyclic Compounds

Spirocycles provide an exciting platform to develop and understand the reactivity and selectivity for a wide variety of catalysts while affording diverse strategies to access molecules with important applications. This review features recent examples in which a spirocenter is formed within the key step of a catalytic asymmetric process, in either an intramolecular or intermolecular fashion. Examples highlight notable spirocyclization strategies and compare the reactivity and selectivity for different classes of chiral organocatalysts and organometallic catalysts.
