Common Name8-hydroxy-5,5,9,13-tetramethyl-3-oxo-12-oxapentacyclo[11.2.1.1¹¹,¹⁴.0¹,¹⁰.0⁴,⁹]heptadecan-6-yl acetate
Description8-Hydroxy-5,5,9,13-tetramethyl-3-oxo-12-oxapentacyclo[11.2.1.1¹¹,¹⁴.0¹,¹⁰.0⁴,⁹]Heptadecan-6-yl acetate belongs to the class of organic compounds known as kaurane diterpenoids. These are diterpene alkaloids with a structure that is based on the kaurane skeleton. Kaurane is a tetracyclic compound that arises by cyclisation of a pimarane precursor followed by rearrangement. It possesses a [3,2,1]-bicyclic ring system with C15-C16 bridge connected to C13, forming the five-membered ring D. 8-hydroxy-5,5,9,13-tetramethyl-3-oxo-12-oxapentacyclo[11.2.1.1¹¹,¹⁴.0¹,¹⁰.0⁴,⁹]heptadecan-6-yl acetate is found in Isodon lungshengensis. 8-Hydroxy-5,5,9,13-tetramethyl-3-oxo-12-oxapentacyclo[11.2.1.1¹¹,¹⁴.0¹,¹⁰.0⁴,⁹]Heptadecan-6-yl acetate is an extremely weak basic (essentially neutral) compound (based on its pKa).
