A series of N-trifluoroacetyl/pentafluoropropionyl-O-trifluoroethyl/~ntafluoropropyl/heptafluorobutyl ester derivatives of 5-methoxyindole-3-acetic acid (SMIAA) were synthesized. Under electroncapture negative ionization conditions, the N-trifluoroacetyl derivatives were found to yield relatively ab
