Australian Journal of Chemistry
46(6) 933 - 937
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′lR*,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.
