A New Fusicoccane‐Type Norditerpene and a New Indone from the Marine‐Derived Fungus Aspergillus aculeatinus WHUF0198

A new norditerpene named aculeaterpene A (1) and a new indone named aculeaindone A (2), along with eight known compounds 3–10 were isolated from the culture extract of Aspergillus aculeatinus WHUF0198. The structural characterization of compounds 1 and 2 were performed by spectroscopic analysis, including 1D and 2D NMR and HR‐ESI‐MS experiments, whereas the absolute configurations were determined by comparing their experimental or calculated ECD spectra. Compound 1 was the first report of fusicoccane‐based norditerpene, in which the C‐20 was degraded and tured into a hydroxy group.
