http://en.wikipedia.org/wiki/Diels%E2%80%93Alder_reaction

This article explains the Diels-Alder reaction pretty well in my honest opinion.
Do you have any specific questions?

I have a problem with Diels-Alder  synthesis:The diene synthesis of 1,3-butadiene and ethyl esters of fumaric acid and maleic are obtained with molecular formula C12H18O4 compounds. Give the structures of compounds formed and detailed in the relationship are byproducts of the two reactions.

That seems fairly straightforward - if you read the "cis addition" and "endo addition rule" section of the reference contra provided, can you put your starting materials together in ways that make sense?

Seems to me that it asking for the products of 1,3-butadiene when it undergoes DA reaction with fumaric and maleic. The products are different in terms of stereochemistry.
