The asym. total synthesis of (+)-waihoensene (I), which has a cis-fused [6,5,5,5] tetracyclic core bearing an angular triquinane, a cis-fused six-membered ring, and four contiguous quaternary carbon atoms, was achieved through a sequence of chem. reactions in a stereochem. well-defined manner. The total synthesis features the following: (1) Cu-catalyzed asym. conjugated 1,4-addition; (2) diastereoselective Conia-ene type reaction; (3) diastereoselective intramol. Pauson-Khand reaction; (4) Ni-catalyzed diastereoselective conjugated 1,4-addition; and (5) radical-initiated intramol. hydrogen atom transfer (HAT). Control experiments and d. functional theory calculations support the proposed HAT process.
