title: TFP as a ligand in Au(I)-catalyzed dihydropyran synthesis. Unprecedented rearrangement of dihydropyrans into cyclopentenones.
abstract: Dihydropyrans have been prepared by the cyclisation of easily accessible propargyl vinyl ethers with (TFP)AuCl/AgBF(4) as a catalyst in high yields. These compounds undergo acid-catalysed rearrangement into cyclopentenone derivatives.
