Triacetoxyperiodinane → HCID 24800521, compound

Participants

Reaction Steps

2-Cyano-6-(2-(1-hydroxy-3-(4-(phenoxymethyl)phenyl)propyl)oxazol-5-yl)pyridine (133 mg, 0.323 mmol) was dissolved in anhydrous CH2Cl2 (4 mL) and Dess-Martin periodinane (205 mg, 0.485 mmol) was added. The reaction solution was stirred at room temperature under an atmosphere of Ar for 2.5 h. The addition of saturated aqueous NaHCO3 quenched the reaction and the organic layer was washed with saturated aqueous Na2S2O3 and saturated aqueous NaCl. The organic layer was dried over Na2SO4 and the solvent was removed in vacuo. The crude product was purified by flash chromatography (SiO2, 0-1% MeOH/CH2Cl2) to provide 2-cyano-6-(2-(3-(4-(phenoxymethyl)phenyl)propanoyl)oxazol-5-yl)pyridine as a yellow solid (98 mg, 74%): 1H NMR (CDCl3, 500 MHz) δ 8.04 (dd, 1H, J=8.1, 0.9 Hz), 7.98-7.95 (m, 2H), 7.68 (dd, 1H, J=7.7, 0.9 Hz), 7.37 (d, 2H, J=8.0 Hz), 7.30-7.26 (m, 4H), 6.97-6.94 (m, 3H), 5.03 (s, 2H), 3.74 (t, 2H, J=7.5 Hz), 3.12 (t, 2H, J=7.5 Hz); 13C NMR (CDCl3, 150 MHz) δ 187.3, 158.7, 157.5, 151.4, 147.8, 140.0, 138.4, 135.1, 134.3, 129.4, 128.5, 128.7, 128.1, 127.8, 123.0, 120.9, 116.5, 114.8, 69.7, 40.7, 29.3; HR ESI-TOF m/z 410.1501 (M+H+, C25H19N3O3, requires 410.1499).
