Versuchsvorschrift
Synthesized using compound 44a (150 mg, 0.70 mmol), CDI (570 mg, 3.52 mmol) and acetonitrile (9 mL) according to Method E. Crude product was purified by flash chromatography on silica-gel using a mixture of hexane/ethyl acetate (3:1) as eluent. White solid. Yield: 116 mg, 54%. 1H NMR (CDCl3, 500 MHz): δH (ppm)=1.04 (t, J=7.4 Hz, 3H), 2.01-2.15 (m, 1H), 2.22 (dt, J=14.3, 7.2 Hz, 1H), 5.92 (t, J=7.1 Hz, 1H), 7.09 (dd, J=1.6, 0.6 Hz, 1H), 7.41-7.51 (m, 4H), 7.75-7.80 (m, 2H), 7.98-8.03 (m, 2H), 8.17-8.19 (m, 1H), 8.74-8.77 (m, 1H); 13C NMR (CDCl3, 125 MHz): δC (ppm)=9.8, 28.7, 79.8, 117.0, 120.3, 126.9, 128.8, 129.3, 130.8, 132.3, 135.0, 137.0, 138.6, 148.0, 148.3, 158.0; MS (ESI): m/z=308.30 [M+H]+.
