Question

What alkene would yield 2,2-dimethoxycyclopentane-1,3-dicarbaldehyde on treatment with${\mathit{O}}_{\mathbf{3}}$followed by ${\left(C{H}_3\right)}_{\mathbf{2}}\mathit{S}$?

Short answer

It involves the reaction of an alkene with ozone, followed by a reducing agent, to form a carbonyl compound.

Step-by-step solution

Ozonolysis

It involves the reaction of an alkene with ozone, followed by a reducing agent, to form a carbonyl compound.

Formation of the product 

The reaction of the given alkene with ozone in the presence of${\left({\mathrm{CH}}_3\right)}_2\mathrm{S}$ gives the desired product.

The reaction is shown below.
