5,9-Dihydroxy-9-methyl-3,6-dimethylene-3a,4,5,6,6a,7,8,9,9a,9b-decahydroazuleno[4,5-b]furan-2(3H)-one

The title compound, C15H20O4, was synthesized from 9α-hydroxyparthenolide (9α-hydroxy-4,8-dimethyl-12-methylene-3,14-dioxatricyclo[9.3.0.02,4]tetradec-7-en-13-one), which was isolated from the chloroform extract of the aerial parts of Anvillea radiata. The seven-membered ri...
