CH, S), 3.66 (m,, JH, J~= 22.0 Hz, 3 J~,~= 2.9 Hz, 1 H, CHO), 4.60 carbodiimide (25 mg, 0.12 mmol). After 4 h at room temperature the dicyclohexylurea was removed by filtration and washed with n-hexane. The collected organic phases were dried over anhydrous sodium sulfate, the solvent was removed under reduced pressure, and the residue was flash chromatographed (n-hexaneldiethy1 ether 982) to give the desired (S)-2- ...
