Abstract
The first synthesis of (-)-mitrephorone A is disclosed along with discussion and study of synthetic strategies. The natural product includes a highly congested hexacyclic ent-trachylobane diterpenoid framework featuring a rare, embedded oxetane. The synthetic analysis presented dissects a number of approaches for the synthesis of the central oxetane, including carbonyl-olefin photocycloadditions, Prins-type cyclizations, and oxidative ring closures. In the successful route, three [4 + 2] cycloadditions enable rapid construction of all carbocycles. A novel late-stage oxidative cyclization of a hydroxy diosphenol with Koser's reagent furnishes the pivotal oxetane moiety.

Abstract
Nickel-catalyzed multiple-component reactions are a promising new type of domino reaction. For instance, a variety of starting materials such as alkenes, alkynes, and unsaturated carbonyl compounds can be connected with high selectivity under reasonably mild conditions. These reactions provide a new route to synthetically important key compounds including dienes, enynes, enol silyl ethers, and carbocycles. Furthermore, an asymmetric version of the reaction is successful. Thus, intermolecular domino reactions should be important reactions for years to come.
