sponge Ircinia oros yielded a new fusarielin analogue (1) together with the known
compounds griseofulvin (4) and dechlorogriseofulvin (5). The structure of 1 was
unambiguously elucidated by comprehensive spectroscopic analysis (1D and 2D NMR, and
mass spectrometry) as well as by comparison with the literature, while the absolute
configuration of 1 was determined on the basis of TDDFT ECD calculations. A further …
