Give a synthesis of target module 7 below using BOTH the starting materials given.  More than one step will be necessary, and you should include reagents and conditions for each step.  You should include at least one reaction that uses organosilicon chemistry, at least one reaction that uses organophosphorus chemistry and at least one reaction that uses organosulfur chemistry.  Also, to the two starting materials shown below, you may use any commonly available commercial reagents. You do NOT need to draw curved arrow mechanisms for your synthesis, but your answer should include a discussion of any issues of chemo-, regio- or stereoselectivity that occur. [12 marks]
