Given the Cosey, HSQC and HMBC experiments assign the 1H NMR spectrum and 13C NMR spectrum signals of the compound. 1H peaks are labelled using lowercase letters and 13C peaks using uppercase. Be aware that the letters of the same peak does not necessarily refer to the position in the molecule. For example, peak a in the 1H and peak A in the 13C NMR are not necessarily assigned to the same number atom. The assignment of protons 4 and...
