Partial synthesis of sesquiterpene lactones: a route to 7,11-ene-13-hydroxyeudesmanolides
摘要:
An efficient partial synthesis of several sesquiterpene lactones has been carried out from costunolide by treatment with trimethyl(phenyl)ammonium perbromide. A selective bromination at the C-11 = C-13 bond provides a new route to 7,11-ene-13-hydroxyeudesmanolides. A synthesis of arbusculin D has been achieved.
