Common Name

(4s,6r,6as,9r,10s,10as)-6,10-bis(acetyloxy)-3-[(acetyloxy)methyl]-6a,9-dihydroxy-6,9-dimethyl-2-oxo-4h,5h,7h,8h,10h-naphtho[4a,4-b]furan-4-yl (2e)-2-methylbut-2-enoate

Description

(4S,10aS)-4,5,6,6a,7,8,9,10-Octahydro-3-(acetoxymethyl)-6beta,10alpha-diacetoxy-6aalpha,9beta-dihydroxy-6,9-dimethyl-4beta-[(E)-2-methyl-2-butenoyloxy]-2H-naphtho[8a,1-b]furan-2-one belongs to the class of organic compounds known as cadinanolides. These are sesquiterpene lactones based on 2-dioxonaphtho[4a,4-b]furan. (4s,6r,6as,9r,10s,10as)-6,10-bis(acetyloxy)-3-[(acetyloxy)methyl]-6a,9-dihydroxy-6,9-dimethyl-2-oxo-4h,5h,7h,8h,10h-naphtho[4a,4-b]furan-4-yl (2e)-2-methylbut-2-enoate is found in Vernonanthura nudiflora. Based on a literature review very few articles have been published on (4S,10aS)-4,5,6,6a,7,8,9,10-Octahydro-3-(acetoxymethyl)-6beta,10alpha-diacetoxy-6aalpha,9beta-dihydroxy-6,9-dimethyl-4beta-[(E)-2-methyl-2-butenoyloxy]-2H-naphtho[8a,1-b]furan-2-one.
