摘要：
A Pt-II-catalyzed intramolecular chemo- and regioselective pentannulation/long-range 1,5-acyl migration reaction is described. This cascade cycloisomerization protocol produces a wide variety of benzofulvene diketones in good to excellent yields with exclusively the Z configuration of the exocyclic double bond of the final product. The O-18 isotope experiment together with C-13 NMR, HRMS, and HMBC analyses confirmed an interesting long-range acyl rearrangement process in this transformation.
