5. Propose a Synthesis for the molecule below. You may use any starting materials containing 6
carbons or less (reagents that aren't incorporated into the final molecule such as PhзP do not
count towards this total, and the starting material can have whatever non-carbon functional
groups you want), and any of the reactions you have learned so far in organic chemistry I, II, and
III. Your final answer should show each step separately, with intermediates and conditions clearly
drawn.
