Divergent Total Synthesis of Denudatine Alkaloids Cochlearenine, Macrocentrine, Dictizine, 15-Veratroyl-17-Acetyl-19-Oxodictizine, and the Proposed Structure of Acochlearine. [PDF]

open access: yesAngew Chem Int Ed Engl
An intramolecular Mannich reaction (A/B/E/F rings) and intermolecular Diels–Alder reactions (C/D rings) afforded a cage‐like hexacyclic core skeleton of denudatine alkaloids. Derivatization of the hexacyclic intermediate enabled the first asymmetric total syntheses of four denudatine alkaloids: (–)‐cochlearenine, (–)‐macrocentrine, (–)‐dictizine, and (–
