2. Propose an efficient synthesis (less than 5 steps) of the following molecule from benzene. You...
Propose an efficient and elegant synthesis of the molecule using only a benzene as your starting material. You may use any alkyl halide or alcohol as your other sources of carbon (excluding HCOCl), and any other reagent you deem necessary. OH Cl
9. Propose an efficient synthesis of each molecule below starting from benzene and any other reagents needed (organic or inorganic) A. CI B. CI NO2 Br
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

Devise a synthesis that will accomplish the following transformation in good yield. Use the given compounds as the only organic source of carbon atoms. You may use any common organic solvents as well as any needed inorganic reagents (14) V. Starting from benzene and any other reagents you need, propose an efficient synthesis of th following compound. (10) VI....
2. Propose a synthesis of the following molecule from benzene. Show the product of each individual step in your synthetic route. Use whatever reagents are required.
3) Propose a synthesis scheme for the following molecule from benzene using any reaction conditions. 4) Propose a synthesis scheme for the following molecule from benzene using any reaction conditions. NH2
Extra Credit Propose an elegant and efficient synthesis of the molecule show below. You may use alcohols of 4 carbons or less as your only source of carbon. H3C CH3 HBr CHs
Problem 3 Propose a synthesis of the following molecule from the given starting material. You may use any reactions we have learned in this course so far, and any reagents containing the carbon atoms you need. If you make a mixture in any of the steps, place a box around the compound you would separate from the mixture, and carry on with your synthesis assuming you can isolate the desired regioisomer. NH2
Please show all of your steps. Thank you! 5 (20 pts). (a) Propose a reasonable synthesis, using indicated diketone as starting material. ini ² and any C4 or less starting materials (SMS) (any reagents are allowed) Hint: as a C3 SM use Br (b) Propose two syntheses, which will use two distinct methods for construction of the 6-membered ring: (1) Crossed-Claisen condensation and (2) Claisen condensation(s). must use this reagent plus any acyclic Cg or less BONUS (5 pts).
