Reaction Steps

General procedure D was used to deprotect 1.15 mmol of 4 and was then immediately coupled to 1.15 mmol of 35. After flash chromatography 0.115 g (0.4 mmol) of the title product was recovered. 1H NMR (500 MHz, CDCl3) δ 7.68-7.55 (m, 2H), 7.34 (dd, J=2.9, 9.5, 2H), 6.73 (d, J=7.7, 1H), 5.16 (p, J=7.2, 1H), 2.63 (t, J=7.7, 2H), 1.66 (d, J=7.2, 2H), 1.61 (s, 2H), 1.30 (dd, J=21.4, 28.1, 10H), 0.87 (t, J=7.0, 3H). 13C NMR (126 MHz, CDCl3) δ 166.89, 143.81, 143.59, 132.58, 132.52, 128.60, 127.34, 124.32, 119.40, 52.60, 48.47, 36.28, 35.81, 31.86, 31.43, 31.38, 29.42, 29.27, 29.23, 22.66, 19.54, 18.65, 14.11.
