The first enantioselective totalsyntheses of prenylflavonoid Diels–Alder natural products (−)‐kuwanon I, (+)‐kuwanon J, (−)‐brosimone A, and (−)‐brosimoneB have been accomplished from a common intermediate based on a concise synthetic strategy. Key elements of the synthesis include a biosynthesis‐inspired asymmetric Diels–Aldercycloaddition mediated by a chiral ligand/boron Lewis acid, as well as
