The following spectral data are provided for a compound with a molecular formula CHaNO;: IR (solution in CHCI), 500 MHz 'H NMR, 125.8 MHz "C NMR, DEPT-90, DEPT-135, COSY, HMQC, HMBC, TOCSY (150 ms mixing time) and NOESY. Also included are select regions of the HSQC-TOCSY spectra with increasing mixing times. All NMR spectra were measured in CDCI, solution. Using these data, determine the structure of the compound and assign all of the H and C resonances to their respective atoms in the structure. Make sure to determine the stereochemistry of the compound and to clearly assign 'H resonances to the appropriate diastereotopic protons.
