A novel abyssomicin analogue compound and method of synthesizing the novel abyssomicin analogue compound are provided. The synthesis method includes the novel abyssomicin analogue compound being simply produced from a mixture of water and a co-solvent with linear precursors. The water molecules in the synthesis method can have dual roles, which are cyclisation followed by hydration via a unique mechanism. Abyssomicins are a family of spirotetronate natural products exhibiting promising bioactivities.
