Total Syntheses of Sappanin‐Based Natural Products Enabled by Pattern Recognition Analysis and Brominative Aromatization

Chemistry – An Asian Journal, EarlyView.
A unified synthetic strategy enables the total syntheses of sappanin‐based natural products from a common privileged intermediate derived from cyclic vinylogous esters. Abstract Described is a concise route to caesappins A and B, urolithin C, and protosappanin A, which share a common sappanin core.
