Catalytic palladium-mediated tetraene carbocyclizations: 1,2- and 1,4-stereochemical control in a polycyclization reaction
摘要:
The palladium-mediated intramolecular diene-to-diene coupling with intramolecular trapping provides a novel route for the stereoselective construction of two new ring via the net 1,4-addition of carbon and oxygen across an internal diene subunit.
