FooDB Nameent-16-Kauren-19-al
Descriptionent-16-Kauren-19-al, also known as ent-kaurenal or kaur-16-en-18-al, 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. ent-16-Kauren-19-al is an extremely weak basic (essentially neutral) compound (based on its pKa).
