The four contiguous all-carbon quaternary centers of waihoensene, coupled with the absence of any traditional reactive functional groups other than a single alkene, renders it a particularly challenging synthetic target among angular triquinane natural products. Here, we show that its polycyclic frame can be assembled concisely by using a strategically selected quaternary center to guide the formation of the other three through judiciously selected C–C bond formation reactions. Those events, which included a unique Conia-ene cyclization and a challenging Pauson–Khand reaction, afforded a 17-step synthesis of the molecule in enantioenriched form. Despite the power of modern chemical synthesis, the preparation of unique, non-functionalized terpenes remains challenging. Here, we show how the strategic use of a minimal number of functional groups, coupled with retrosynthetic planning based on the use of a guiding all-carbon quaternary center to forge three additional such centers as fueled by some unique C-C bond forming steps, can afford an expeditious, 17-step total synthesis of the unique angular triquinane natural product (+)-waihoensene.
