    • Representative procedure: Compound 3 (0.14g, 0.3 mmol) was allowed to mix with Cu(OAc)2-H2O (0.06 g, 0.3 mmol) in THF (2 mL) at room temperature and stirred for 1h, and then benzaldehyde (0.31 mL, 3 mmol) and nitromethane (1.62 mL, 30 mmol) were sequentially added. The mixture was heated to 45 °C and stirred for 72 h, cooled to room temperature, and 0. 1 M HCI was added. The organic phase was separated, and the water phase was extracted with EtOAc (45 mL, The combined organic phases were washed with saturated NaCl, dried over anhydrous Na2SO4 and concentrated, and the residue was purified by column chromatography to give 1-phenyl-2-nitro-ethanol(Yield 0.12 g, 24, α]D2D=+24.6 (c 0.20, CH2l2, 1H NMR (CDCl3, 300 MHz) δ (ppm, 7.39 (m, 5H, 5.47-5.42 (m, 1H, 4.64-4.47 (m, 2H, 2.90 (d, J= 3.9 Hz, 1H, IR (KBr, cm-1):3629, 3421, 3065, 3033, 2918, 1670, 1
