The asymmetricdihydroxylation of several enantiomerically pure 4-substituted allylic 4′-methoxybenzoates proceeds with excellent reagent-controlled diastereoselectivities. This observation, coupled with the high enantio- and regioselectivity provided by the Sharpless asymmetricdihydroxylation of suitably protected dienes, has been used to accomplish the stereocontrolled total syntheses of several
