Assign the peaks in the H-NMR spectra to protons on the corresponding structure of the Diels-Alder Adduct There’s just one step to solve this. Solution Share Step 1 Solution: NOCH3OHOHHH121615141334712111098242356171819222021 1H−NMR of the compound is a...
All three NMR peaks in the carbonyl carbon region were assigned to be attributed to the acetyl groups located at C, C, and Cpositions, from the low magnetic field side. The previous Kamide and Okajima's assignment on Cand Cpeaks was found to be erroneoulsy made by neglecting an ...

Chemical shift values for 1H NMR and 13C NMR are referenced to residual solvent peaks (CHCl3 in CDCl3: 7.26 p.p.m. for 1H, 77.00 p.p.m. for 13C). Chemical shifts are reported in d p.p.m. All coupling constants (J values) were reported in Hertz (Hz). Data for 1H NMR ...
(2 mL). After 5 minutes an additional equal volume of 2N NaOH was added to maintain pH. The reaction was shaken overnight, then dialyzed repeatedly and lyophilized to give the diprotected product. NMR studies show incorporation of the 2 functional groups in the correct ratios. This masked ...
