実験手順

1.02 ml (1.02 mmol, 3.00 eq.) of a 1 M solution of BBr3 in CH2Cl2 was added to a solution of 192.9 mg (0.34 mmol) 3-(2′,2″-Diisobutyl-4-methoxy-3-naphthalen-1-ylmethyl-[1,1′:4′, 1″]-terphenyl-4″-yl)propionitrile (76) in 20 ml dry CH2Cl2 at 0° C. via syringe. After that the solution was stirred for 3 h at 0° C. and then for 12 h at r.t. The reaction mixture was then added to water and extracted with CH2Cl2. The comb. org. fractions were dried over MgSO4 and evaporated. Column chromatography (hexanes/EtOAc (2+1)) yielded 117.9 mg (0.21 mmol, 62.85%) 3-(4-Hydroxy-2′,2″-diisobutyl-3-naphthalen-1-ylmethyl-[1,1′:4′, 1″]terphenyl-4″-yl)propionitrile (32) as a colorless oil. Rf (hexanes/EtOAc (2+1))=0.37. 1H-NMR (500 MHz, CDCl3): δ=0.59 (d, 6H, J=6.62 Hz, 2*CH3), 0.70 (d, 6H, J=6.78 Hz, 2*CH3), 1.50 (m, 1H, CH), 1.65 (m, 1H, CH), 2.32 (d, 2H, J=7.25 Hz, CH2), 2.47 (d, 2H, J=7.25 Hz, CH2), 2.62 (t, 2H, J=7.41 Hz, CH2CH2CN), 2.94 (t, 2H, J=7.41 Hz, CH2CH2CN), 4.47 (s, 2H, CH2Naphthyl), 4.80 (s, 1H, OH), 6.86 (d, 1H, J=8.36 Hz), 6.98-7.16 (m, 9H), 7.38 (m, 1H), 7.43-7.48 (m, 2H), 7.73 (dm, 1H, J=8.73 Hz), 7.83 (m, 1H), 8.06 (m, 1H).
