反応手順
The title compound was synthesized from 5-formylfuran-3-boronic acid pinacol ester (878 mg, 3.95 mmol), and benzyl diethyl phosphate (1.25 g, 5.14 mmol) using the same conditions used to synthesize 5-benzyl-furan-2-carbaldehyde, with the exception that TPP and Pd(OAc)2 were dissolved in 2:1 CH3CN/isopropyl alcohol. Purification by flash chromatography yielded 4-benzyl-furan-2-carbaldehyde as a white solid (300 mg, 41%). 1H NMR (400 MHz, CDCl3) δ ppm 9.56 (s, 1 H) 7.29-7.38 (m, 3 H) 7.24-7.28 (m, 2 H) 7.17 (d, J=3.5 Hz, 1 H) 6.19 (d, J=3.6 Hz, 1 H) 4.07 (s, 2 H).
