실험 절차

A solution of 5 (0.47 g, 1.3 mmol), 1,1-diphenylprop-2-yn-1-ol (0.66 g, 3.2 mmol), CuI (0.05 g, 0.3 mmol), Pd(PPh3)2Cl2 (0.18 g, 0.3 mmol), PPh3 (0.07 g, 0.3 mmol), and Et3N (4 mL) in anhydrous DMF (4 mL) was stirred for 16 hours at 70° C. under N2 atmosphere. The reaction mixture was partitioned between water and EtOAc. The combined organic layer was dried over MgSO4, filtered and concentrated in vacuo. MPLC purification (Hexanes:EtOAc/80:20) of the residue gave 6 as a pale yellow solid (0.49 g, 87%). 1H NMR (400 MHz, CDCl3) δ 9.88 (s, 1H), 7.50-7.52 (m, 4H), 7.36 (s, 1H), 7.24-7.30 (m, 8H), 7.04 (m, 2H), 5.69 (s, 2H), 3.80 (s, 3H), and 3.65 (s, 1H); 13C NMR (100 MHz, CDCl3) δ 185.16, 160.72, 144.07, 136.84, 128.91, 128.72, 128.33, 127.91, 127.79, 127.05, 126.23, 124.96, 116.97, 103.35, 75.37, 75.27, 52.15, and 50.38.
