Reaction Steps

A solution of (2R,3S)—N-(cyclopropylmethyl)-N-[(1R,2R)-2-hydroxycyclohexyl]-3-phenyloxirane-2-carboxamide (117b) (1.05 g, 3.33 mmol) in 125 mL acetonitrile/TFA (0.4%) was stirred for 6 hours. After evaporation the crude oil was purified by chromatography (CHCl3) to afford the title compound (850 mg, 81%). HPLC: 4.54 min (Method B). 1H NMR (300 MHz, CDCl3) δ0.37-0.44 (m, 2H), 0.49-0.57 (m, 2H), 0.85 (m, 1H), 1.03 (m, 1H), 1.14-1.50 (m, 2H), 1.66-1.80 (m, 2H), 1.83-2.02 (m, 1H), 2.03-2.16 (m, 2H), 3.32 (dd, 1H, J=7 Hz, J=14 Hz), 3.60 (in 1H), 3.74 (m, 1H), 3.85 (dd, 1H, J=7 Hz, J=14 Hz), 4.34 (m, 1H), 4.60 (m, 1H), 7.27-7.40 (m, 5H).
