Fill in the boxes over each arrow with the letter that
corresponds to the reagents needed to perform each step of the
multistep synthesis show below. Reagents may be used more than
once, or not at all. Pay close attention to the numbered carbons in
the starting material, and be sure that your answer accounts for
the position of these carbons in the final product.
