摘要

Abstract: 2-(Phenylsulfony1)-1, 3-dienes were stereo-and regioselectively functionalized via Michael addition of nucleophiles and subsequent addition of nucleophiles and/or electrophiles to the resulting allylic sulfones. The second nucleophile is introduced via a palladium-catalyzed or a cuprate-promoted nucleophilic substitution of the allylic sulfone. The strategy was applied to the synthesis of a Monarch butterfly pheromone. The ...
