Abstract:

Arynes generated from the corresponding o-(trimethylsilyl) aryl triflates have emerged as powerful synthons in organic synthesis. Aryne annulation reactions with intramolecular C-H functionalization can be a powerful method for the synthesis of polycyclic compounds. We developed a novel palladium-catalyzed domino Heck/aryne carbopalladation/C-H functionalization reaction using in situ generated arynes, in which three new C-C bonds and a carbon quaternary center are formed. This methodology affords moderate to excellent yields of heterocycle-fused 9, 10-dihydrophenanthrenes.
