| Preclavulone lactones were isolated from Japanese soft coral, Stolonifer Clavularia viridis Quoy and Gaimard. Iwashima_M et al. | |
| Preclavulone lactone I was synthesized from (S)-(-)-malic acid. Iwashima_M et al. | |
| Preclavulone lactone may possibly be biosynthesized from preclavulon A. Clavulones may be biosynthesized from preclavulone lactones via clavulolactones by oxygenation at C-12, dehydration between C-7 and C-8, and esterification at C-1 and C-4. Iwashima_M et al. | |
