The structures of two new cembranoids, sinulariol E (1) and mayolide E
(2), isolated from the soft coral Sinularia mayi, were derived from t
he spectroscopic data and by chemical correlation; application of the
pyridine-induced deshielding effect, for the H-1 NMR study of the cemb
ranoid allylic alcohol system, is described.
