Versuchsvorschrift

934 mg (3.90 mmol) of ((1R,4S)-4-azido-cyclopent-2-enyloxy)-tert-butyl-dimethyl-silane (35) were dissolved in 16 mL of tetrahydrofuran and 1.13 g (4.29 mmol) of triphenylphosphine were added. After the addition of 2 mL of water, the reaction mixture was stirred at room temperature, until the reaction was complete. Sat. sodium chloride solution was added, the layers separated and the organic layer was evaporated in vacuo. The crude product was purified by silica gel chromatography to yield 890 mg of the title compound (36). Rt=1.02 min (Method C). Detected mass: 214.3 (M+H+).
