Rapid construction: We report the first successful implementation of a catalytic tandem carbocyclization/annulation cascade reaction (e.g., see scheme) using acetal–allene or ketal–allene substrates through a dealkoxylative mode. This gold catalysis enables a rapid stereocontrolled construction of oxacyclic or carbocyclic frameworks.
