Devise a synthesis for the compound below using cyclopentane as your only source of carbon. You may use any other reagents. The most efficient route includes a Diels-Alder reaction, two radical halogenation reactions and two elimination reactions.
Explain why cyclopentadiene (pKa 16) is many orders of
magnitude more acidic than cyclopentane (pKa > 50). (Hint: Draw
the structural formula for the anion formed by removing one of the
protons on the −CH2− group, and then apply the Hückel criteria for
aromaticity.)

what are the products formed from addition of HCL to 1,3-cyclopentadiene?
Cyclopentadiene is a better diene for a Diels-Alder reaction that a non-cyclic diene like 1,3-pentadiene. However, this increased reactivity also causes cyclopentadiene to dimerize much more easily. Explain the why cyclopentadiene is more reactive than 1,3-pentadiene.

devise a synthesis
Treatment of cyclopentane-1,3-dione with a base followed by addition of methyl iodide affords a mixtures of 2-methylcyclopentane-1,3-dione, 2,2-dimethylcyclopentane-1,3-dione and 3-methoxy-2-cyclopenten-1-one. Explain with the aid of a mechanism how each product is formed.
When 1,3-cyclopentadiene is treated with HBr, the temperature does not have an influence on the identity of the major product. Explain.
