A specimen of Phyllidia picta collected from Bali, Indonesia, contained the axane sesquiterpenoids pictaisonitrile-1 (3) and pictaisonitrile-2 (4). The planar structures were elucidated using 1D and 2D NMR spectroscopy, while relative configurations were established using NOESY correlations, coupling constant data, and comparison with literature data.5enPublisher Copyright: © 2017IsocyanideNMRPhyllidiaPhyllidiellaSesquiterpene201810.1016/j.fitote.2017.10.00385036498725
