摘要
An investigation of the natural products chemistry of the red alga Laurencia marianensis Yamada, a species whose chemistry has not previously been described in the literature, yielded the new metabolite 1-[(3'S*,3a'R*,4'R*,7'S*,7a'S*)-7'-bromo-7a'-methyl-3'-(1''-methylethyl)octahydro-1'H-inden-4'-yl]ethanone (1) and the known metabolites deoxyprepacifenol (2) and pacifenol (3). The full n.m.r. characterization of (2) and (3) is reported for the first time.
