Keeping with the theme of autumn, one of Dr. Danahy’s favorite molecules is caffeic acid due to its presence in pumpkins. This structure serves as an antioxidant and is one of many found within pumpkins. Despite its name, it bears no resemblance to caffeine. Answer the following questions about caffeic acid. a.One of the alkene protons is unusually downfield with a chemical shift of 7.45 ppm. Determine which of these protons the signal belongs to and explain why you assigned it this way.
A chemist records an ESI accurate mass spectrum of an intermediate during a synthesis. The desired compound is C29H31N3O8S. She sees a peak(M+H)^(+) on her ESI-TOF LCMS at 583.1733. The two possibilites for the incorrect feature are A: incoporation of a deuterium at an acidic site from the CDCL3 used for NMR she ran immedately prior LC-MS or B: An amide was hydrolyzed to an acid. Assuming the mass spectrometer is well calibrated, which of these two options is supported by the data. Be sure to explain your answer.
