Sicker et al. regarding the study of Pseudopelletierine (9-Methyl-9-azabimiccyclo[3.3.1]nonan-3-one). We boarded the NMR data in the subchapter with didactical purposes, doing an analysis of 13 C NMR chemical shifts in a spectral/structural approach. We established the structure by doing a 13 C NMR “Pure Shift” analysis if the term is worth.enCarbon-13 NMRSpectral analysisChemistryChemical shiftStereochemistryA COLLATERAL APPROACH ON THE 13 C NMR ANALYSIS OF PSEUDOPELLETIERINE, AN ALKALOID FROM POMEGRANATEarticle
