A concise synthesis of two scyphostatin analogues is achieved from readily available ortho-substituted phenols. Key features include an asymmetric and biomimetic hydroxylativephenoldearomatization (HPD) reaction promoted by a chiral salen-type bis(λ5-iodane) reagent, followed by an in situ regio- and diastereocontrolled epoxidation.
