A two-step synthesis of virstatin reactions are given. Give the yield and % yield of each synthesis. Make a labeled drawing of the equivalent hydrogens for each product. Using the NMR drawings given for each structure, describe how the hydrogens are seen on the NMR by chemical shift, integration, and splitting. Make sure your NMR matches the structure of the product you are proposing. For example: “the triplet at 4ppm, integrating to 2, represents the methylene group (Ha) attached to the nitrogen, as it deshielded by the electronegative element and is split by the neighboring methylene group. If you did not make the intended product in step one of the two step synthesis, explain why it did not matter in regards to further reacting the products to form virstatin. Data Mass of 1,8-naphthalimide used: 0.2528g Mass of potassium carbonate used: 0.2624g Recovered virstatin ethyl ester: 0.2602gMass of virstatin ethyl ester used in step 2: 0.1066g Mass of recovered virstatin: 0.0035g…

Following is a 1H-NMR spectrum of2-butanol, Explain why the CH2 protons appear as a complex multiplet rather than as a simple quintet.
A student was given from the list of the compounds below A, B and D blindly and asked to identify them all. He treated each of them with Brady's reagent (2,4-ditrophenylhydrazine) and isolated a bright yellow compound for one of them, but the other two gave false negatives. The student reasoned that the false negatives may be due to sterics and, on further thinking, it dawned on him that he might be able to rule out one of the false negatives with the haloform test. What compound did he find compatible with the haloform test? That compound did indeed give a false negative in the Brady test. Which of the other two was positive in the Brady test? A = haloform B = Brady A = haloform D = Brady B = haloform A = Brady B = haloform D = Brady D = haloform A = Brady D = haloform B = Brady
