Natural Product Identification
Common Name2,16-dihydroxy-5,5,9-trimethyl-14-methylidenetetracyclo[11.2.1.0¹,¹⁰.0⁴,⁹]hexadecan-15-one
Description2,16-Dihydroxy-5,5,9-trimethyl-14-methylidenetetracyclo[11.2.1.0¹,¹⁰.0⁴,⁹]Hexadecan-15-one 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. 2,16-dihydroxy-5,5,9-trimethyl-14-methylidenetetracyclo[11.2.1.0¹,¹⁰.0⁴,⁹]hexadecan-15-one is found in Croton kongensis. 2,16-Dihydroxy-5,5,9-trimethyl-14-methylidenetetracyclo[11.2.1.0¹,¹⁰.0⁴,⁹]Hexadecan-15-one is an extremely weak basic (essentially neutral) compound (based on its pKa).
