7. Although the Diels-Alder reaction generally occurs between an electron-rich diene and an electron- deficient dienophile, it is also possible to have inverse-demand Diels-Alder reactions between suitable electron-deficient conjugated double bonds and electron-rich alkenes. These reactions are particularly useful because they allow for the incorporation of heteroatoms into the new six-membered ring. Predict the products of each inverse-demand Diels-Alder reaction below. Be sure your products reflect the correct stereochemistry. If more than one regio-isomer is possible, draw both.
