Compound 9t was synthesized by a procedure similar to that described for 9a using 3-chloropentaphenone (8k, 2.7 g, 0.014 mol), TBDMSOTf (3.5 mL, 15 mmol), and Et3N (3.1 mL) in CH2Cl2 (25 mL). After purification, 4.18 g (96%) of the title product was isolated as colorless oil: 1H NMR (CDCl3) δ 7.47-7.44 (m, 1H), 7.38-7.32 (m, 1H), 7.30-7.28 (m, 1H), 7.25-7.22 (m, 1H), 5.18 (t, 1H, J=7.2 Hz), 2.20 (q, 2H, J=7.5 Hz), 1.54-1.38 (m, 2H), 1.02 (s, 9H), 1.00-0.90 (m, 3H), −0.05 (s, 6H); 13C NMR (CDCl3) δ 148.0, 141.8, 133.9, 129.2, 127.6, 125.9, 123.9, 113.0, 28.3, 25.8, 22.8, 14.0, 0.0, −4.01.
