Common Name

(3as,4s,5s,5ar,6r,9s,9as,9br)-6-(acetyloxy)-9-hydroxy-5a,9-dimethyl-5-{[(2z)-2-methylbut-2-enoyl]oxy}-3-methylidene-2-oxo-octahydronaphtho[1,2-b]furan-4-yl (2s,3s)-2,3-dimethyloxirane-2-carboxylate

Description

(3AS,4S,5S,5aR,6R,9S,9aS,9bR)-6-(acetyloxy)-9-hydroxy-5a,9-dimethyl-5-{[(2Z)-2-methylbut-2-enoyl]oxy}-3-methylidene-2-oxo-dodecahydronaphtho[1,2-b]furan-4-yl (2S,3S)-2,3-dimethyloxirane-2-carboxylate belongs to the class of organic compounds known as eudesmanolides, secoeudesmanolides, and derivatives. These are terpenoids with a structure based on the eudesmanolide (a 3,5a,9-trimethyl-naphtho[1,2-b]furan-2-one derivative) or secoeudesmanolide (a 3,6-dimethyl-5-(pentan-2-yl)-1-benzofuran-2-one derivative) skeleton. (3as,4s,5s,5ar,6r,9s,9as,9br)-6-(acetyloxy)-9-hydroxy-5a,9-dimethyl-5-{[(2z)-2-methylbut-2-enoyl]oxy}-3-methylidene-2-oxo-octahydronaphtho[1,2-b]furan-4-yl (2s,3s)-2,3-dimethyloxirane-2-carboxylate is found in Calostephane divaricata. Based on a literature review very few articles have been published on (3aS,4S,5S,5aR,6R,9S,9aS,9bR)-6-(acetyloxy)-9-hydroxy-5a,9-dimethyl-5-{[(2Z)-2-methylbut-2-enoyl]oxy}-3-methylidene-2-oxo-dodecahydronaphtho[1,2-b]furan-4-yl (2S,3S)-2,3-dimethyloxirane-2-carboxylate.
