Write the reagents required to bring about each reaction next to the arrows shown.
Next, record any regiochemistry or stereochemistry considerations relevant to the
reaction. You should also record any key aspects of the mechanism, such as forma-
tion of an important intermediate, as a helpful reminder. You may want to keep
track of all reactions that make carbon-carbon bonds, because these help you build
large molecules from smaller fragments. This especially applies to the reactions in…
Provide the reasonable steps to achieve the following synthesis.
Identify which compound is more acidic. Justify your choice.
