abstract = "A new halogenated diterpene, dolabellol A (1), was isolated from the opisthobranch Dolabella auricularia. The planar structure of dolabellol A was elucidated by NMR spectroscopic analysis and chemical reactions. The absolute stereochemistry was determined by single-crystal X-ray diffraction studies.",

note = "Funding Information: halogen and two oxygen atoms, suggested an ether linkage in the molecule, which was supported by the IR absorption at 1021 cm¹1. On the basis of COSY and HMQC cross peaks, three spin systems were assigned (Figure 1). One of the cyclohexane rings (ring A; C1C6) was deduced from the HMBC correlations (H4b/C2, H4b/C6, H16/C2, H16/C4), while the 7-oxabicyclo[2.2.1]heptane moiety (rings B and C) was assigned on the basis of HMBC correlations (H13a/C15, H18/C10, H18/C12, H19/C14, H19/C10, H20/C10, and H20/C14). This ring system was confirmed by comparison of 13C NMR data of 3¤,6¤-epoxycycloaurapten.8 HMBC correlations among H6/C17 and H8a/C10 connected these two parts via the linking part (C7C9).
