Draw one product structure for the following Diels Alder reaction. For ONLY the chirality centers with D and C(=O)H groups, specify the stereochemistry via wedge-and-dash bonds. (D is deuterium, an isotope of hydrogen. Include it in your drawing by either double clicking on an atom and typing \"d\" or by choosing D in the bottom row of the atoms menu.)
