  Construction of Epidithiodioxopiperazines by Directed Oxidation of Hydroxyproline-Derived Dioxopiperazines

  摘要：

  Functionalization of the angular methine carbon of hydroxyproline-derived dioxopiperazines by a radical-promoted C-H bond oxidation, which is directed by a proximal (bromomethyl)silyl group, is described. This regioselective oxidation is the key step in a new synthesis of epidithiodioxopiperazines.
