  Total synthesis of angelone enabled by a remarkable biomimetic sequence

  摘要：

  The natural product angelone was readily accessed with a remarkable biomimetic journey that sequentially features carbonyl formation elimination, 6 pi-electrocyclization, visible light-promoted singlet O-2 Diels-Alder reaction, Kornblum-DeLaMare-type peroxide rearrangement, 6 pi-electrocyclic ring-opening, and conjugative addition-elimination as the key steps. With key intermediates isolated and characterized, this study stands to reveal a rare system in which bio-inspired synthetic strategies were found to mirror experimental realities.
