    • Typical procedures for thiiranaton of 1 with 4 and Ac20 in a metal-salt solution: To a Et20 solution of a metal salt (3.0 mL) was added 1 (20.l mg, 73 μmol) and 4 (17.2 mg, 73 μmol, After the mixture was cooled to -15 °C, Ac20 (6.8 μL, 73 μmol) was added dropwise to the mixture. After stirring for 45 h at the same temperature, the reaction was quenched by the addition of ice water. After the mixture was diluted with Et20, the organic layer was separated, washed with H2O three times, dried over MgS04, and evaporated under reduced pressure. The residue was chromatographed on a column of silica gel and the column was eluted with hexane to give a mixture of 1, 2, and 3, and with CH2Cl2/hexane (l:5) to give a mixture of oxiranes 5 and 6. The product ratios were estimated by 1H NMR
