Need help understanding what compounds to use when doing
multistep syntheses.
5. (Multistep synthesis) For each of the following multistep syntheses, provide an efficient multistep synthesis of the target compound from the starting compound. More than one reaction is required for this synthesis. You may use any inorganic compounds that you need. For cach functional group transformation, give all necessary reagents, solvents, and catalysts; give a structural formula of the organic reactant and the major organic product(s). Show stercochemistry appropriately...

S. Show how you would prepare the following compound using an organometallic reagent. You may use any hydrocarbons, organohalides, alcohols and/or carbonyl compounds that have five of fewer carbon atoms You may also use any needed reagents and solvents OH This one as well. He quits grading when you get two mistakes. 6. Propose a synthesis of the following compound using a Wittig reaction.

Part IV - Multistep Synthesis cont'd Propose a synthesis of compound B from (R)-2-chlorobutane. When choosing your synthetic steps, you can use any hydrocarbon with three or fewer carbon atoms, any solvents or inorganic reagents, and any organic reagents that do not contribute carbon atoms to the carbon skeleton in the product. Clearly show the required reagents and the product of each step. You do not need to show mechanistic (curved) arrows. CI (R)-2-chlorobutane B

Multistep Synthesis (9 pts) Show how to convert benzene into at least one of the molecules below using any reagent. You should be able to do this in three steps but this is not a required minimum or maximum. If you are not sure of an intermediate step put down structures and as much as you know about reagents to maximize partial credit. You may attempt more than one and the best will be graded. It is ok if a...
