5,8-Dimethyl-3-methylene-2-oxo-3,3a,4,5,5a,6,8a,8b-octahydro-2H-1-oxa-s-indacene-5-carbaldehyde
The title compound, C(15)H(18)O(3), was synthesized from 9α-hydroxyparthenolide (9α-hydroxy-4,8-dimethyl-12-methylene-3,14-dioxatricyclo[9.3.0.0(2,4)]tetradec-7-en-13-one), which was isolated from the chloroform extract of the aerial parts of Anvillea radiata. The five-membered lactone ring h...

Sumario: | The title compound, C(15)H(18)O(3), was synthesized from 9α-hydroxyparthenolide (9α-hydroxy-4,8-dimethyl-12-methylene-3,14-dioxatricyclo[9.3.0.0(2,4)]tetradec-7-en-13-one), which was isolated from the chloroform extract of the aerial parts of Anvillea radiata. The five-membered lactone ring has a twisted conformation, while the six- and five-membered rings display chair and envelope conformations, respectively. The dihedral angle between the two five-membered rings is 50.57 (11)°. |
