実験手順

To a solution of 20 (215 mg, 0.422 mmol) in CH2Cl2 (4.2 mL) and TFA (98 μL, 1.26 mmol) was added methyl-3-mercaptopropionate (56 μL, 0.506 mmol). The solution was stirred at ambient temperature for 5 hours when LCMS analysis indicated complete conversion of the starting materials to the products. The solution was dried under reduced pressure and azeotroped with CH2Cl2 three times to provide the product 23 as a yellow solid. 1H NMR (300 MHz, CDCl3) δ 2.30-2.38 (m, 4H), 3.63 (s, 3H), 4.04 (s, 3H),4.42 (d, 1H, J=15 Hz), 5.33 (d, 1H, J=15 Hz), 5.49 (s, 1H), 7.05 (t, 2H, J=9 Hz), 7.38 (dd, 2H, J=5, 8 Hz), 7.59 (dd, 1H, J=4,9 Hz), 8.53 (d, 1H, J=8 Hz), 8.91-9.01 (m, 1H); 19F NMR (282.6 MHz, CDCl3) δ 62.6; EI MS (m/z) 457.3 [MH+], 479.2 [M+Na].
