Cinnamoylphenethylamine 1H-NMR chemical shifts: a concise reference for ubiquitous compounds.
1H-NMR data of 25 cinnamoylphenethylamine derivates were recorded and compared in order to assign signals unequivocally without additional spectroscopic data. The spectra provide a key for the rapid identification of these ubiquitous natural products. The compounds isomerize rapidly in UV light, producing a characteristic upfield shift of the olefinic protons consistent with distorted planarity of the cis cinnamate, and this requires special attention during preparative work.
