Participants

Reaction Steps

Dess Martin Periodinane (0.688 g, 1.62 mmol) was added to a solution of the [(R)-2-cyclopropylmethanesulfonyl-1-(2,6-dihydroxy-cyclohexylcarbamoyl)-ethyl]-amide (0.32 g) in DCM (10 mL) and the mixture was stirred at room temperature for 3 hours then treated with resin bound Na2S2O3 (1.5 mmol/g, 1.9 g) and stirred at room temperature for a further 24 hours. The reaction mixture was diluted with DCM (20 mL), then filtered. The filtrate was washed with a solution of 0.25 M Na2S2O3, then with saturated NaHCO3, then dried (MgSO4), and then evaporated under reduced pressure. The residue was subjected to column chromatography eluting with a mixture of ethyl acetate and heptane to give morpholine-4-carboxylic acid [(R)-2-cyclopropylmethanesulfonyl-1-(6-oxo-cyclohex-1-enylcarbamoyl)-ethyl]-amide. 1H NMR (CDCl3): 9.00 (s, 1H), 7.78 (t, 1H), 6.18 (d, 1H), 4.9 (m, 1H), 3.85 (m, 1H), 3.77–3.62 (m, 4H), 3.58–3.45 (dd, 1H), 3.48–3.36 (m, 4H), 3.0 (d, 2H), 2.55–2.42 (m, 4H), 2.08–1.97 (m, 2H), 1.2 (m, 1H), 0.8–0.7 (m, 2H), 0.6–0.4 (m, 2H). MS: 414 (MH+).
