Reaktionsschritte

To a solution of triphenylphosphine (3.83 g, 14.61 mmol) in THF (40 mL) at 0° C. was added DEAD (2.54 g, 14.61 mmol) drop wise and the reaction mixture was stirred for 20 minutes. Compound 76 (1.78 g, 9.61 mmol) was added to the reaction mixture and stirred for an additional 20 minutes. Then acetone cyanohydrin (1.319 mL, 14.42 mmol) was added, stirred for 1 h at 0° C. and 18 h at room temperature. The reaction mixture was concentrated then purified by flash chromatography to afford 77 (0.972 g, 52%).
