A palladium-catalyzed tandem C−H activation/biscyclization reaction of propargylic carbonates with terminal alkynes was determined, which allowed the tetracyclic benz[a]anthracene framework to be constructed with high regioselectivity. A possible mechanism for this tandem C−H activation/biscyclization process was discussed.
