The tetrapetalone family of natural products contains a series of 4-5 contiguous stereocenters arranged about a cyclohexadienone core. Our strategy imagines the control of all stereocenters from the control of one. Attempts at initial diastereoselective control via an ortho-quinone methide intermediate will be examined. Stereoselective oxidative dearomatization as a means to complete the core as part of a model study will also be highlighted.
