Intramolecular Remote C–H Activation via Sequential 1,4-Palladium Migration To Access Fused Polycycles
2019-08-15T15:35:25Z (GMT) by
An unprecedented intramolecular remote C–H activation via sequential 1,4-palladium migration with an aromatic ring as a conveyor has been described. This reaction provides an efficient route to construct diverse polycyclic frameworks in moderate to good yield via palladium-catalyzed remote C–H activation/alkene insertion, arylation, alkenylation, and the Heck reaction. The preliminary mechanistic studies revealed that the 1,4-palladium migration process was reversible.
