Homework Answers
Diels-Alder reaction:
The most well known Diels-Alder reaction is the thermal [4+2] cycloaddition reaction. The pericyclic reaction proceeds stereospecifically and in a single step.
The diene in the given Diels-Alder reaction is 1,3-cyclohexadiene and dienophile is fumaric acid. COOH groups in fumaric acid are trans to each other and they are also trans to each other in the product.
The reaction is given in the image below:
