✦ Synopsis

Certain unexpected features have been reported in the litterature for room-temperature NMR spectra of some P-acylindole alkaloids (1,2,3,Q). P-Acylindole alkaloids and their derivatives in table I can be grouped in three classes according to the spectral characteristics of their msthyl signals.

Class Am : compounds whose NMR spectra can be interpreted straightforwardly on the basis of their accepted structures.
