Versuchsvorschrift

A solution of iodine (I2, 0.063 g, 0.24 mmol) in THF (2 mL) was added dropwise to an ice bath cooled solution of 12a (0.114 g, 0.172 mmol) in THF (3 mL). After the addition, the reaction was stirred at 0° C. for 1 h. Following standard workup with CH2Cl2, the crude product was purified by FC (EtOAc/Hexanes, 25/75) to give a light yellow solid 13a (0.037 g, 48%). 1H NMR δ8.22 (d, 1H, J=2.1 Hz), 8.10 (d, 1H, J=2.1 Hz), 7.38 (d, 2H, J=8.8 Hz), 6.92 (d, 1H, J=16.3 Hz), 6.72 (d, 1H, J=16.3 Hz), 6.71 (d, 2H, J=8.8 Hz), 4.72-4.67 (m, 1H), 4.54-4.44 (m, 3H), 3.93-3.69 (m, 8H), 3.00 (s, 6H). 13C NMR δ160.4, 150.5, 144.6, 144.55, 129.8, 129.5, 127.8, 125.3, 118.8, 112.6, 85.1, 81.7, 80.6, 71.3, 71.1, 70.8, 70.5, 69.6, 67.1, 40.6. HRMS calcd for C21H26FIN2O3 (M+), 500.0972; found, 500.0959.
