title: Total syntheses of enokipodins A and B utilizing palladium-catalyzed addition of an arylboronic acid to an allene.
abstract: The enantioselective total syntheses of enokipodins A and B, alpha-cuparenone-type sesquiterpenoids with antimicrobial activity, have been achieved. The key step is the enantiospecific construction of the quaternary carbon center using a palladium-catalyzed addition of an arylboronic acid to an allene followed by an Eschenmoser-Claisen rearrangement.
