The first total syntheses of (+/-)-arthrinone, (+/-)-1-dehydroxyarthrinone, and (+/-)-3a,9a-deoxy-3a-hydroxy-1-dehydroxyarthrinone, antifungal metabolites from the coprophilous fungus Cercophora sordarioides, were accomplished in a stereoselective manner. The ring systems of these metabolites, which were rare among natural products, were efficiently and diastereoselectiveiy assembled using the [2,3]Wittig rearrangement and Diels-Alder reaction as the key steps.
