Get started for freeBoth NaBH4 and NaBD4 are commercially available, and D2O is common and inexpensive. Show how you would synthesize the following labelled compounds, starting with propanone.
The following road-map problem centers on the structure and properties of A, a key intermediate in these reactions. Give structures for compounds A through J.
Assume you are a research physiologist trying to unravel a serious metabolic disorder. You have fed your lab animal Igor a deuterium-labelled substrate and now need to analyze the urinary metabolites. Show how you would differentiate these four deuterated aldehydes using mass spectrometry. Remember that deuterium has mass 2.
In the absence of water, ophthalaldehyde has the structure shown. Its strong IR absorption is at 1687 cm-1; the proton NMR data are shown by the structure. In the presence of water, a new compound is formed that has a strong IR absorption around 3400 cm-1 and no absortion in the C=0 region. propose a structure of X consistent with this information and suggest how X consistent with this information and suggest how X was formed.
Show how you would accomplish the following synthetic conversions. You may use any additional reagents and solvents you need.
