摘要：

Two new rearranged sesquiterpenoid metabolites, 2,5-epoxybrasil-1(6)-en-9-ol [3] and 5,9-dihydroxybrasil-1(6)-en-7-one [4], have been isolated along with laurencienyne and brasilenol from the Mediterranean marine alga Laurencia obtusa. They possess the unusual skeleton of brasilane. Their structures were determined by detailed spectral analysis. The relative configurations were assigned by NOESY spectroscopy and molecular mechanics calculations. © 1990, American Chemical Society. All rights reserved.
