a. Circle the chiral centers in the following molecule and identify them as R or S Suggest a second component for synthesis of the molecule above via a Diels-Alder reaction (i.e. completer the reaction below) c. Is the configuration of your starting material in part b, E or Z? d. The concept of aromaticity (i.e. 4n + 2 pi electrons stable, aromatic; 4n electrons = unstable, antiaromatic) can be used to understand reaction like the Diels-Alder and related reactions. Use...
