Swinholide-A (a) a novel 22-membered macrolide has been isolated from a Red Sea sponge. The structure of the tetraformate () has been determined on basis of spectral data using 2D-NMR correlations.

1H and 13C NMRspectra of the novel marine macrolide swinholide‐A, which provide the basis for its structure elucidation, have been completely assigned by parallel use of 1D and homo‐ and hetero‐nuclear 2D NMR techniques. Swinholide‐A (1) probably a polyketide, is a 22‐membered macrolide embodying a dihydropyran ring and a 10‐carbon side‐chain ending with a substituted tetrahydropyran ring. The high
