资源简介：
A PtII-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 18O isotope experiment together
with 13C NMR, HRMS, and HMBC analyses confirmed an interesting
long-range acyl rearrangement process in this transformation.
