A convergent approach to the total synthesis of (–)-invictolide, a component of the
queen recognition pheromone of Solenopsis invicta, is described. Key steps involve the desymmetrization of a bicyclic olefin with Brown’s
chiral hydroboration, C–C bond formation, 1,3-syn reduction, and oxidative lactonization of a 1,3,5-triol with TEMPO/PhI(OAc)2.
