Aplysinadiene and (r,r) 5 [3,5-dibromo-4-[(2-oxo-5-oxazolidinyl)] methoxyphenyl]-2-oxazolidinone, two novel metabolites from aplysina aerophoba synthes
Two novel constituents, biogenetically derived from dibromotyrosine, were obtained from a sponge . The structure of aplysinadiene was established on the basis of its spectral properties and by synthesis of and its isomers and . The structure and absolute configuration of the oxazolidinone was established by X-ray diffraction analysis as (R,R) 5 [3, 5-dibromo-4-[(2-oxo-5- oxazolidinyl)] methoxyphenyl]-2-oxazolidinone
