摘要

Pd-catalyzed oxidative cyclizations of 1, 6-enynes have found useful applications in organic synthesis,[1] but such reactions with Au and Pt catalysis remain largely unexplored.[2] Goldcatalyzed cycloisomerizations of 1, 5-and 1, 6-enynes provide uncommon and useful carbocyclic frameworks.[3] In the presence of organic oxidants, most enynes fail to produce oxidative cyclization products because oxidations of hypothetical gold–carbenoid ...
