The trachylobane diterpenes
Tetracyclic diterpenes such as ent-kaur-16-ene (4), ent-beyer-15-ene (5) and ent-atis-16-ene (6) are an important group of natural diterpenes. The trachylobane family is related to these compounds and characterized by a pentacyclic carbon.skeleton (7) with a tricyclo 3,2,1,0 octane system for the rings C, D, and E. Some authors, using the nomenclature proposed by Rowe (1968), have named this series as ent-13,16- cycloatisane. In this paper we have reviewed the natural occurrence, isolation, biosynthesis, chemistry, spectroscopic properties and bioactivity of the trachylobane class of diterpenes.
