Sodium periodate → HCID 86669708, compound

Participants

Reaction Steps

To an ice-cooled solution of (4S)-2-oxo-3-benzyl-4-isopropyl-1,2,3-oxathiazolidine (6.00 g, 25.07 mmol) in acetonitrile (45 mL) and water (45.0 mL) was added ruthenium chloride (5.20 mg, 0.025 mmol) followed by sodium periodate (8.04 g, 37.6 mmol). The mixture was stirred for 1 h as ice bath melted and the reaction was gradually warmed to room temperature. The mixture was extracted with ether (3×50 mL). The combined organic extracts were washed with brine (100 mL), dried (MgSO4), filtered, then concentrated. The resulting oil was purified by silica gel flash column chromatography to give the title compound (1.9 g) as a colorless oil. LCMS m/z=256.2 [M+H]+. 1H NMR (400 MHz, CDCl3) δ 0.86 (d, J=7.1 Hz, 3H), 0.90 (d, J=7.1 Hz, 3H), 1.83-1.95 (m, 1H), 3.41-3.45 (m, 1H), 4.23-4.28 (m, 2H), 4.39-4.44 (m, 2H), 7.35-7.43 (m, 5H).
