An efficient one step, retro‐biomimetic procedure for the synthesis of natural products having the atisane structure is described (Scheme 2), natural products which are components of medicinal plants and possess relevant biological activity. Their structures were confirmed by chemical transformations and spectral data. The starting materials were the known ent‐kaur‐16‐en‐19‐oic acid (1) and ent‐trachyloban‐19‐oic
