report the concise and divergenttotalsyntheses of several naturally occurring dihydrochalcones and 5-deoxyflavones from readily available starting materials. The divergent strategy is based around manipulation of a common chalcone scaffold and features application of Algar–Flynn–Oyamada oxidation and benzoquinone C–H activation methodologies. These are the first reported totalsyntheses of these biologically
