## Abstract The mass spectra of four of the six 1,4βdihydroxyβ Ξ^6,7^βoctalins are reported. The spectra differ considerably, depending on the configuration of the hydroxyl groups. The relative amounts of 1β3,1β4, transannular 1β3 and hydroxylβhydroxyl elimination of water from the molecular ions w
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
