Iriomoteolides-1b and -1c, 20-Membered Macrolides from a Marine Dinoflagellate <i>Amphidinium</i> Species

Abstract

Two 20-membered macrolides, iriomoteolides-1b ( 1) and -1c ( 2), have been isolated from a marine dinoflagellate Amphidinium sp. (strain HYA024), and the structures were elucidated on the basis of detailed analyses of 2D NMR data and chemical correlation.
