Using acetylene as your ONLY source of carbons, show how you would synthesize the following compound. Note: any alkyl halides, alcohols, or other organic compounds must be made first from acetylene. You may use any other inorganic reagent to perform your synthesis. This is a multistep synthesis NOT a mechanism !

Using any intermediate from the above sythesis (Hint: The biggest one would work the best), show how you would convert the intermediate to the following compound.
