Abstract
A highly selective and efficient Pt-catalyzed pentannulation reaction beginning from propargylic esters is described. The key to this reaction is the use of a PtCl2(PPh3)2/PhIO catalyst combination that allows the in situ generation of Pt-carbenoid intermediates, which lead to good yields (61-84%) of the desired pentannulated compounds.
