The spirooxindole ring system of citrinadin A has been synthesized with excellent control over the absolute stereochemistry at the spirocenter. The key step involves a novel diastereoselective DMDO-mediated oxidative rearrangement employing an 8-phenylmenthol chiral auxiliary on the indole nitrogen.
