Versuchsvorschrift

The alcohol 44 (0.55 g, 0.8 mmol) was reacted (Method B) with pyridinium dichromate (0.36 g, 0.96 mmol) and 4 Å molecular sieves (0.4 g) in anhydrous CH2Cl2 (4 mL). The product was obtained (flash column chromatography 80% EtOAc/20% n-hexane) as a white foam (0.36 g, 66%). 1H NMR (CDCl3) δ 7.22 (m, 3H), 7.07 (d, J=7.5 Hz, 2H), 6.50 (s, 1H), 5.95 (m, 3H), 5.70 (dd, J=3, 10 Hz, 1H); 5.30 (m, 5H), 4.90 (d, J=13 Hz, 1H), 4.60 (m, 4H), 4.45 (m, 1H), 3.92 (s, 3H), 3.55 (m, 8H), 2.50 (m, 2H), 2.30 (m, 1H), 2.10 (m, 4H).
