We report herein the asymmetric total synthesis of periglaucines A–C, N,O‐dimethyloxostephine and oxostephabenine. The key strategies used include: 1) a RhI‐catalyzed regio‐ and diastereoselective Hayashi‐Miyaura reaction to connect two necessary fragments; 2) an intramolecular photoenolization/Diels–Alder (PEDA) reaction to construct the highly functionalized tricyclic core skeleton bearing a quaternary...
An asymmetric photoenolization/Diels–Alder (PEDA) reaction between electron‐rich 2‐methylbenzaldehydes and unsaturated γ‐lactones was developed to directly construct the basic tricyclic core of aryltetralin lactone lignans. This methodology enabled the first asymmetric total synthesis of aglacins A, B, and E and revision of the absolute configuration of these natural lignans. The strategy was also...
