    • This structural assignment is based on the assumption that no complete rearrangement from O-Tf to N-Tf isomers occurs under the mass spectrometry conditions. Within the accurate mass measurement, no second peak or shoulder within the measured peak was observed.

    • note
    • At temperatures below -50 °C the reaction slows down considerably. If base is added in these cases, triflation of the base competes with triflation of the lactam. At higher reaction temperatures e.g. -20 °C and higher (as established in the NMR experiments cited) the yield of 5 is lowered.
