2 General procedure for the preparation of 3(2H)-furanones and 2,3-dihydro-4H-pyran-4-ones To a solution of γ-hydroxyalkynones 1 or δ-hydroxyalkynones 3 (0.50 mmol) in toluene (2.5 ml, 0.20 M) were added (p-cf 3 C 6 H 4 ) 3 PAuCl (17.5 mg, mmol) and AgOTf (6.4 mg, mmol) in this order at room temperature. The reaction mixture was stirred at room temperature until the complete consumption of 1 and then quenched with sat. aq. NH 4 Cl. The organic materials were extracted with EtOAc, and the combined organic extracts were washed with brine, dried over MgSO 4, and evaporated in vacuo. The residue was purified by column chromatography (silica gel, usually hexanes/etoac) to give 3(2H)-furanone 2 and 2,3-dihydro- 4H-pyran-4-ones 4.
