Total and unambiguous assignment of the 1H NMR spectrum of piperovatine [6‒(4‒methoxyphenyl)‒N‒(2‒methylpropyl)‒2,4‒hexadienamide] was carried out using conventional 1D NMR methods and spectral spin–spin simulation. Based on these data, the complete assignment of the 13C NMR chemical shift values was made by a 13C/1H chemical shift correlation diagram and conventional considerations for the quaternary carbon atom.
