Reaction Steps

To a stirred solution of 1-naphthalen-2-yl-hex-5-en-1-yn-3-ol (1.00 g, 4.50 mmol) under an atmosphere of nitrogen in toluene (100 mL) was added platinum chloride (0.06 g, 0.22 mmol, 5 mol %); the resulting black mixture was stirred at 80° C. for 24 hr. TLC indicated that the reaction was complete. The organics were concentrated in vacuo to afford a black residue. The crude material was purified by flash chromatography (SiO2, ethyl acetate:petroleum ether 40-60; 10%:90%) to afford the desired compound as a yellow oil (0.64 g, 64%). 1H NMR (400 MHz, CDCl3) δ ppm 0.70 (1H, t, J 4.0 Hz, CH), 0.83-0.86 (1H, m, CH), 1.41-1.44 (1H, m, CH), 2.44 (1H, d, J 18.0 Hz, CH), 2.75 (1H, d, J 18 Hz, CH2), 2.86-2.91 (1H, m, CH), 3.05 (1H, d, J 18.0 Hz, CH), 7.24-7.26 (1H, m, ArH), 7.44-7.49 (2H, m, ArH), 7.63 (1H, s, ArH), 7.80 (1H, d, J 8.0 Hz, ArH).
