Typical Reaction Procedure (see, Table 1, Entry 4) A typical reaction procedure is as follows: to a stirred solution of the allyltrimethylsilane (85.1 μL, 0.54 mmol) and 1 (101.2 mg, 0.18 mmol) was added TMSOTf (6.6 μL, 0.036 mmol) in MeCN-CH2Cl2 (1:1, 3 mL) at -78°C in the presence of dry CaSO4 (ca. 100 mg) in an Ar atmosphere. The resulting mixture was stirred for 2 h. The reaction was then quenched by the addition of a sat. NaHCO3 solution (5 mL, The reaction mixture was extracted with EtOAc, and the organic layer was washed with H2O and a sat. NaCl solution. After the organic layer was dried over anhydrous Na2SO4, the solvent was evaporated under reduced pressure. The crude product was purified by preparative silica gel TLC (EtOAc-hexane, 1:4) to give 4 (61.2 mg, 58, Ketopyranoside 2: [α]D21 +64.4 c 1.12, CHCl3, 1H
