Reaktionsschritte

2-Propanethiol (98.0 μL, 1.1 mmol) was dissolved in THF (250 μL), and the mixture was cooled to 0° C. NaH (12.6 mg, 527 μmol) was slowly added in four portions and the mixture was stirred at room temperature for 10 minutes. (S)—(R)-3-Oxiranylpyrrolidine-1-carboxylic acid t-butyl ester (75 mg, 350 μmol) was dissolved in THF (0.1 mL) and added to the mixture. The resulting solution was placed in a microwave reactor for 30 minutes at 100° C., then cooled to room temperature. Hexanes (3×10 mL) was added, followed by water (10 mL). The organic layer was collected, dried over Na2SO4, filtered, and concentrated. The crude product was purified by column chromatography (0-100% EtOAc in hexanes) to yield the title compound as a clear oil (60 mg).
