The 8-membered ring framework of vinigrol, a unique tricyclic diterpene isolated as a novel antihypertensive compound from a culture of Virgaria nigra, was efficiently synthesized employing an SmI2-induced intramolecular coupling. It is particularly noteworthy that the 8-membered carbocycle was cyclized in quantitative yields under non-high-dilution conditions.
