The same procedure was followed as for the production of 2e in Example 17: it was performed with 0.20 g (0.75 mmol) of alcohol 1i, 3 cm3 of water and 0.12 g (3 mmol) of sodium hydroxide. Reaction time: 1 h 15 min; ether extraction (4×7 cm3). After treatment, 0.15 g of epoxide 2g were obtained (macrobore GC purity>97.5%), having a yield of 80%.
