実験手順

To a vial charged with 6-hydroxy-2-naphthonitrile (3.38 g, 0.02 mol, 1.0 eq.), cis-4-tert-butylcyclohexanol (6.24 g, 0.04 mol, 2.0 eq.), PPh3 (10.5 g, 0.04 mol, 2.0 eq.) and toluene (20 mL), was added DIAD (12 mL, 0.06 mol, 3.0 eq.) under nitrogen atmosphere at r.t. and stirred for 15 h. Water was added and extracted with EtOAc. The organic layer was purified by silica gel chromatography (PE:EA=10:1) to give the title compound (9.0 g, 86%) as a slight yellow solid. EDI-MS (M+1)+: 308.0. 1H NMR (400 MHz, CDCl3) δ 8.12 (s, 1H), 7.78-7.73 (m, 2H), 7.54 (dd, 1H), 7.22 (dd, 1H), 7.14 (s, 1H), 4.33-4.30 (m, 1H), 2.29-2.25 (m, 2H), 1.93-1.90 (m, 2H), 1.48-1.26 (m, 2H), 1.25-1.10 (m, 3H), 0.91 (s, 9H).
