Question

3 Draw eAer reaction were complete. Indicate the nucleophile and electrophile in the first step. Hint-there should be three steps, with two arrows in each step the mechanism for the reaction of the alcohol and the anhydride, assuming it occurred after the 6 pts) if 4) Draw the most favorable conformation of the diene starting material. What implication does this have for the energy of the reaction? (2 pts) 5) Cyclopentene could be used in this reaction in place of maleic anhydride, but the reaction would not be as rapid a) Draw this reaction. Note that without the anhydride functional group, the alcohol will be unchanged (2 pts) b) Why is maleic anhydride more reactive than cyclopentene would be (even without the alcohol reaction being involved)? (1 pt) Consider the stereochemistry of the product a) How many stereoisomers are theoretically possible with 4 stereocenters? (1 pt)
