反应详情

A mixture of N-(2-Hydroxyethyl)-2-pyrrolidone (5.00 g, 38.8 mmol) and triacetoxyperiodinane (24.6 g, 58.0 mmol) in CH2Cl2 was stirred at ambient temperature for approximately 64 hours. The reaction mixture was evaporated in vacuo and the residue was triturated with Et2O. After filtration of the solids, the mother liquor was evaporated in vacuo to provide the product as a crude oil: 1H NMR (CDCl3) δ 9.60 (1H, s), 4.16 (2H, s), 3.46 (2H, t, J=7 Hz), 2.45 (2H, t, J=8 Hz), 2.11 (2H, m).
