Provide a reasonable synthesis
Question (2)- Propose a reasonable synthesis of 9 starting from 7 and 8 using any other reagents you might require. (15 pts) OH 7 он
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
Part 2: 1) Starting with a compound with 6 (or less carbons) propose a synthesis for the assigned compounds. Provide all reagents and show intermediates (3 points) COOH CYNO
Propose an efficient synthesis of 2-Bromo-5-nitrotoluene from benzene. Hint: 3 steps. Consider directing effects of substituents. Show intermediates and reagents, the mechanism is NOT required Toluene is the common name for methylbenzene
Show the most efficient synthesis of the product from the starting material. Show all reagents your need over each arrow, and draw all products and intermediates (do not combine steps). You do not need to show the mechanism for any steps. Show all molecules synthesized along the way, and pay attention to stereochemistry. If a racemic mixture is produced in any step, show both products formed. If you make a mixture of regioisomers in any of the steps, place a...
1.) Propose a synthesis for the following general reactions. You may use any other organic or inorganic reagents needed. For each step, show the reagents used and the intermediate formed (Note: I do not need to see any arrow-pushing, only starting materials, reagents, intermediates, and the final product) a.) For each aromatic ring, you must start with a plain benzene. он он CI он
(3) Propose an efficient synthesis of target molecules (a) and (b). All of the carbons in the targets must come from one of the compounds below. Draw the structure of the product formed after each synthetic step. Do not write mechanisms. Note Points off for long, inefficient syntheses Нас CH3I OEt OEt H-C CH methyl iodide ethyl 2-butenoate ethyl acetoacetate he ptane-2,6-dione H2C он CH
Propose the starting material for each product from a molecule with the given formula in the reactants box. You do not have to show mechanisms, but use any reagents you require for each problem. Each problem is ONE OF TWO retrosynthetic steps to the starting materials and all steps should be described CH, Br C Hia 4. Propose a mechanism for the reaction below, showing the movement of every pair of electrons. Draw in an energy diagram, labeling, with structures,...
(14) V. Starting from benzene and any other reagents you need, propose an efficient synthesis of th following compound. (10) VI. 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
