Try retro-Diels Alder from the starting material to give two molecules of cyclopentadiene. Then, reaction of cyclopentadyene with methyl acrylate in a normal Diels-Alder reaction

Thanks for the advice, do you know any books or materials that have these types of exercises? Thank you

These look like pericyclic reactions. I think Karty organic chemistry has a good chapter about pericyclic reactions. Klein organic chemistry has a few interesting easy examples, which could be a good way to start. The ultimate book is probably the tiny "Pericyclic reactions" by Fleming, but the solutions manual is vague and doesn't tell you the answers in an easy way. Fleming is the most advanced one.

All of these books you could probably find on the internet for free but I cannot condone such behavior.
