Which diene and dienophile would you choose to synthesize the following compound?

Question

Quizplus · Accepted Answer

The synthesis of the target compound requires the formation of a six-membered ring through a Diels-Alder reaction. To achieve this, we want to choose a diene that can form a stable cyclic transition state with the dienophile. Choice II, cyclopentadiene, is a highly reactive diene that can easily form a stable transition state with a variety of dienophiles. The dienophile in this case is an electron-deficient alkyne, which can participate in a Diels-Alder reaction with cyclopentadiene to form the desired six-membered ring.
