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.)

See explaination

Explanation:

We can define the Diels-Alder reaction as a conjugate addition reaction of a conjugated diene to an alkene (the dienophile) to produce a cyclohexene.

Please kindly check attachment for the step by step solution of the given problem.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
