Abstract

A synthetic approach to the isocopalane diterpenes ent-spongian-16-one, ent-isoagatholactone, and anisodorin 5 is presented. ent-Spongian-16-one was prepared by using a tricyclic diterpene building block as the starting material. Furthermore, ent-spongian-16-one was easily converted into ent-isoagatholactone and anisodorin 5 through organic transformations.
