Hi everyone,

I try this retrosynthetic analysis, could you take a look? Does it look right?
Thanks!

I would quibble with where you put the squiggly lines.
The very first step, what you wrote implies an aldehyde rather than the acid. Move the line to the C-O bond to give an acid and a "C⁺" unit as retrons. You therefore need an alcohol and an acid.
The second point is the Diels-Alder reaction, are you sure of the regioselectivity?
Otherwise ok. My points are really minor.

I appreciate your response a lot. Thanks!
