摘要：

A new method for the formation of spirocycles is described using a sequential Ireland-Claisen/Metathesis strategy to construct spirocyclic systems. Optimization of the Ireland-Claisen conditions provides the key metathesis substrates. The metathesis reactions were highly regioselective by virtue of steric hindrance in the substrate olefins.
