摘要

The structure of this compound as an N-acyl (and not an S-acyl) derivative is clearly established by its IH-NMR spectra. The multiplicity and relative intensity of signals corresponding to CH-and NH-group protons confirms structure II. Indeed, the NH proton spectral signal was observed in the form of a doublet at 6.74 ppm (3JNH, C N-7.6 Hz) due to the spinspin interaction with the CH proton, which appears at 4.87 ppm (quartet). The ...
