资源简介:
The first total syntheses
of taiwaniadducts B, C, and D have been
accomplished. Two diterpenoid segments were prepared with high enantiopurity,
both through Ir-catalyzed asymmetric polyene cyclization. A sterically
demanding intermolecular Diels–Alder reaction promoted by Er(fod)3 assembled the scaffold of taiwaniadducts B and C. A carbonyl-ene
cyclization forged the cage motif of taiwaniadduct D at a late stage,
providing over 200 mg of this compound.
