First Total Synthesis of (-)-Circumdatin H, a Novel Mitochondrial NADH Oxidase Inhibitor

Abstract

An efficient and highly convergent synthesis of the mitochondrial NADH oxidase inhibitor (-)-circumdatin H is described. The strategy employs the intramolecular Eguchi aza-Wittig protocol as a key step to install the crucial central core BC ring system, leading to the first total synthesis of the target molecule.
