โœฆ Synopsis

The mass spectral data of four isoprenylated indole alkaloids containing a piperazinedione group, neoechinuline, cryptoechinuline C, and A and echinuline, isolated from Aspergillus amstelodami cultures, and of tivo derivatives obtained by catalytic hydrogenation of neoechinuline and echinuline, are reported and discussed. Their fragmentation patterns are strongly dependent upon the presence of a single or a double bond between C-8 P and C-9.

The modes of fragmentation of perchlorylbenzene (C6H6C10s) and its perdeutero derivative under electron impact are reported and discussed. The occurrence of the [C,H,O]and [C,H,O]+ ions is accounted for in terms of a novel phenyl migration from chlorine to oxygen.

## Abstract Studies of both high and low resolution spectra, and of metastable decompositions occurring in both the first and second fieldโ€free regions of the mass spectrometer have led to a postulated scheme for the fragmentation of acridine under electronโ€impact.
