Procedure

2,3-Dihydro-4H-thiopyran-4-one (1.50 g, 13.1 mmol, synthesized as described in Richards et al. J. Org. Chem. 46, 4836-4842 (1981)) was dissolved in CH2Cl2 (130 mL) and triethylamine (5.47 mL, 39.4 mmol) was added. tert-Butyldimethylsilyl trifluoromethanesulfonate (3.62 mL, 15.8 mmol) was then added. After 10 minutes, the volatiles were removed in vacuo at 25° C. The resulting yellow oil was passed through a short column of SiO2 eluting with 3% TEA in hexanes to yield 1.82 g (7.97 mmol, 61%) of compound 1A as an orange oil.
