    • 5 is a well-documented trick to enhance chemical shift difference for prochiral protons in (thio)amides, (thio)ureas, (thio)carbamates (such as in compounds 2, 3, and 4), and dithiocarbamates. All these functional groups present a positive charge on the nitrogen and are very sensitive to ASIS. For other examples see
