11. Propose a synthesis for each compound below. You must write in all necessary reactants, reagents, and solvents to receive full credit. Your starting materials must be 3 carbons or less. If you use an ionic or organometallic species, you must show how it was synthesized from a neutral, covalent species. Any species that adds carbon to your product must be synthesized from a molecule of 3 carbons or less. Only show the steps of your synthesis- do not put...
Starting only from organic reagents of 4 carbons or fewer, propose an efficient synthesis for the molecule below. You may use any necessary solvents and inorganic reagents, and can assume that all products can be isolated as needed. If only one product is to be taken on to a new step, indicate which one.
2. Propose an efficient synthesis (less than 5 steps) of the following molecule from benzene. You may use any additional material and show all intermediates. Br HO
4. Propose an efficient synthesis of the molecule below starting with benzene. You can use any other reagents you want. NOTE: Some reactions produce ortho- and para-products. It is allowable to just take ONE of the products and use it in the next synthesis or claim it as the final product (we assume that ortho- and para-products can be separated). (3 points) CH2CH2CH Br
9. Extra Credit (2 points) Propose a synthesis of the following molecule. Use the required starting material and any reagents (including any alkyl halides). Solve on the back!
Propose an efficient synthesis of the compound shown below, starting from acetylene and methyl iodide. You may use any other reagents as necessary, but all carbons in the product must originate from acetylene and methyl iodide.
