Description

(1S,2R,3R,5R,10S,11R,12R,15R,16R)-10-(acetyloxy)-16-[(5S)-5-[(2R)-3,3-dimethyloxiran-2-yl]-2-oxo-2,5-dihydrofuran-3-yl]-2,6,6,11-tetramethyl-8-oxo-7-oxapentacyclo[13.3.1.0¹,¹⁵.0²,¹².0⁵,¹¹]Nonadecan-3-yl acetate belongs to the class of organic compounds known as limonoids. These are highly oxygenated, modified terpenoids with a prototypical structure either containing or derived from a precursor with a 4,4,8-trimethyl-17-furanylsteroid skeleton. All naturally occurring citrus limonoids contain a furan ring attached to the D-ring, at C-17, as well as oxygen containing functional groups at C-3, C-4, C-7, C-16 and C-17. (1s,2r,3r,5r,10s,11r,12r,15r,16r)-10-(acetyloxy)-16-[(5s)-5-[(2r)-3,3-dimethyloxiran-2-yl]-2-oxo-5h-furan-3-yl]-2,6,6,11-tetramethyl-8-oxo-7-oxapentacyclo[13.3.1.0¹,¹⁵.0²,¹².0⁵,¹¹]nonadecan-3-yl acetate is found in Simarouba amara. Based on a literature review very few articles have been published on (1S,2R,3R,5R,10S,11R,12R,15R,16R)-10-(acetyloxy)-16-[(5S)-5-[(2R)-3,3-dimethyloxiran-2-yl]-2-oxo-2,5-dihydrofuran-3-yl]-2,6,6,11-tetramethyl-8-oxo-7-oxapentacyclo[13.3.1.0¹,¹⁵.0²,¹².0⁵,¹¹]Nonadecan-3-yl acetate.

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as limonoids. These are highly oxygenated, modified terpenoids with a prototypical structure either containing or derived from a precursor with a 4,4,8-trimethyl-17-furanylsteroid skeleton. All naturally occurring citrus limonoids contain a furan ring attached to the D-ring, at C-17, as well as oxygen containing functional groups at C-3, C-4, C-7, C-16 and C-17.
