Four α-methylene-γ-lactone derivatives, designated as mayolide A to mayolide D, were isolated from the soft coral Sinularia mayi. From the spectroscopic data and correlations to known compounds, they were shown to be cembranoid (2, 3, 4) and unprecedented secocembranoid (1) lactone derivatives. Their conformations and relative configurations are discussed on the basis of the common and characteristic unclear Overhauser effect (NOE) fearures.
