Absolute configuration of eremophilenolides from Hertia cheirifolia
摘要:
The absolute configurations of 8alpha-methoxy-10beta-hydroxyeremophilenolide and 8beta,10beta-dihydroeremophilenolide from Hertia cheirifolia were determined by transformation into (-)tetrahydroligularenolide.

enantioselective synthesis of eremophilane sesquiterpenes was developed starting fromS-(+)-carvone 3, using a conjugate addition-annelation sequence. The synthesis of R-(−)-ligularenolide 1 was accomplished in a staightforward manner with the annelation of the lactone as the last step. For the synthesis of the progesterone receptor ligand R-(−)-PF1092C 2 a different strategy was followed in which first the lactone
