Resultado principal
Herein, we disclose a unified synthetic approach that culminates in the first concise enantioselective total syntheses of (−)-ohioensin A and putative (+)-ohioensin C, as well as the flavonoids (+)-myristinins A and B/C and (+)-caesalpinflavan A. The synthetic strategy hinges on the development of novel methodologies, including a chiral biphenol-catalyzed enantioselective conjugate addition of alkenyl and aryl boronic acids to 2-hydroxynitrostyrenes, a stereodivergent cyclization to procure both cis- or trans-2,4-disubstituted benzodihydropyrans, and an intramolecular deaminative aromatic homolytic substitution.
