NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

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.
