Fluorination of kaurenoic acid derivatives by remote functionalization

Kauranoids and related tetracyclic diterpenoids have recently shown an incr easing interest because of the discovery of new biological activities that can be modified by the introduction of a fluorine atom. In this article it is described the stereospecific fluorination of the kauranols 6 and 7 by re mote functionalization at the "unactivated" C-7 position.
