Gold‐Catalyzed Dealkoxylative Carbocyclization/[3+3] Annulation Cascade of Acetal–Allene or Ketal–Allene Substrates

Abstract

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. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
