  Synthesis and absolute stereochemistry of marine nor-sesquiterpene austrodoric acid

  摘要：

  An enantiospecific synthesis of the nor-sesquiterpene austrodoric acid 1, recently isolated from an Antarctic marine mollusk, has been achieved. The synthetic strategy was based on the ring contraction of a suitable homo-drimanic epoxide,3, easily obtained from commercial (+)-sclareolide 4. The absolute configuration of natural austrodoric acid, not determined previously, has been now established by analyzing the CD profile of synthetic 1, which was the same as the natural compound.

  Synthesis of Acuminolide and 17-O-Acetylacuminolide from (+)-Sclareolide

  摘要：

  The synthesis of natural acuminolide and 17-O-acetylacuminolide is reported, Commerically available (+)-sclareolide was converted to epoxy alcohol 3, which upon acid-catalyzed cyclization afforded tricycle 14. Reaction of 14 with O-1(2) in the presence of a hindered base gave an inseparable mixture of acuminolide 1a and 16-epiacuminolide 1b in a 70:30 ratio. Chromatographic separation of the diacetates of 1a and 1b afforded pure 18a and 18b, An analogous reaction sequence was used in the synthesis of 17-O-acetylacuminolide (2a) and 16-epi-17-O-acetylacuminolide (2b).
