실험 절차

490 mg (1.46 mmol) Trifluoro-methanesulfonic acid 4-(2-Cyanoethyl)-2-isobutyl-phenyl ester (6), 505 mg (2.09 mmol, 1.4 eqv) crude 3-Benzyl-4-methoxy-benzene-1-boronic acid (22) and 169.4 mg (0.15 mmol, 0.1 eqv) Pd(Ph3P)4 were dissolved in 20 ml DME/EtOH (9+1). 1.46 ml (2.92 mmol, 2 eqv) of a 2 M aq. Na2CO3-solution was added to this yellow solution and the resulting mixture was heated at 80° C. for 17 h. After concentrating the mixture in vacuo the residue was taken up in water and extracted with CH2Cl2. The comb. org. fractions were dried over MgSO4 and evaporated. Column chromatography (Hexanes/EtOAc (3+1)) yielded 290.8 mg (0.76 mmol, 52%) 24 as a clear oil: Rf (Hexanes/EtOAc (3+1)) 0.34; 1H NMR (400 MHz, CDCl3) δ 0.63 (d, 6H, J=6.70 Hz), 1.55 (m, 1H), 2.35 (d, 2H, J=7.33 Hz), 2.57 (t, 2H, J=7.45 Hz), 2.88 (t, 2H, J=7.45 Hz), 3.79 (s, 3H), 3.92 (s, 2H), 6.82 (d, 1H, J=8.34 Hz), 6.92 (d, 1H, J=2.15 Hz), 6.96-7.20 (m, 9H); LRMS (EI) m/z 383 (13), 335 (15), 293 (23), 214 (17), 187 (21), 161 (20), 160 (100), 145 (35), 144 (35), 105 (50), 91 (58), 77 (11); HRMS (EI) Calcd. for C27H29NO: 383.224914. Found: 383.225267.
