実験手順

134.6 mg (0.27 mmol) Trifluoro-methanesulfonic acid 3-benzyl-4′-(2-Cyano-ethyl)-2′-isobutyl-biphenyl-4-yl ester (54), 96.9 mg (0.33 mmol, 1.24 eq.) 2-(3-isobutyl-4-methoxyphenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (11) and 46.7 mg (40 μmol, 0.15 eq.) Pd(Ph3P)4 were dissolved in 7 ml DME/EtOH (9+1). To this yellow solution 0.27 ml (0.54 mmol, 2.00 eq.) of a 2 M aq. Na2CO3-solution was added and the resulting mixture was heated at 80° C. for 19 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 (6+1)) yielded 122.9 mg (0.24 mmol, 88.26%) 3-(3′-Benzyl-2,3″-diisobutyl-4″-methoxy-1,1′:4′,1″-terphenyl-4-yl)propanenitrile (55) as a clear oil. Rf (hexanes/EtOAc (6+1))=0.20. 1H-NMR (500 MHz, CDCl3): δ=0.69 (d, 6H, J=6.62 Hz, 2*CH3), 0.84 (d, 6H, J=6.62 Hz, 2*CH3), 1.63 (m, 1H, CH), 1.83 (m, 1H, CH), 2.42 (d, 2H, J=7.25 Hz, CH2), 2.44 (d, 2H, J=7.25 Hz, CH2), 2.61 (t, 2H, J=7.41 Hz, CH2CH2CN), 2.93 (t, 2H, J=7.41 Hz, CH2CH2CN), 3.81 (s, 3H, OCH3), 3.98 (s, 2H, CH2Ph), 6.81 (d, 1H, J=8.51 Hz), 6.96 (m, 2H), 7.00-7.18 (m, 10H), 7.24-7.26 (d, 1H, J=7.57 Hz). MS (EI): m/z=517 (10), 516 (45), 515 (100), 472 (10), 381 (8), 91 (20). HR-MS (EI): Calcd. for C37H41NO: 515.318814. Found: 515.319235.
