approach to a series of sesquiterpene mono- and bistropolones, including (−)-epolone B, (+)-isoepolone B, (±)-dehydroxypycnidione, and (−)-10-epi-pycnidione. Alongside the development of a general strategy to access this unique family of metabolites were computational modeling studies that justified the diastereoselectivity observed during key cycloadditions. Ultimately, these studies prompted stereochemical
