The structure of spiropentadiene
The structure of spiropentadiene is shown below; it undergoes a Diels-Alder reaction with two molar equivalents of 1,3-cyclopentadiene. Spiropentadiene is unstable because of its great ring strain. Although cyclopropane rings are retained in the product, they have less ring strain than cyclopropene rings.
