Versuchsvorschrift
Methyl 2,3,4-tri-O-benzyl-6-O-(4′-{(2S,3R)-1-(4-fluorophenyl)-3-[(3S)-3-(4-fluorophenyl)-3-hydroxypropyl]-4-oxoazetidin-2-yl}biphenyl-3-yl)-α-D-glucopyranoside (70 mg, 0.08 mmol) was dissolved in absolute ethanol (3 mL). 10% Pd/C (wet, 14% w/w) was added and the vessel sealed. The solution was degassed by evacuation and flushing with hydrogen gas at balloon pressure. The reaction was monitored by TLC (1:1 hexane-ethyl acetate). Upon completion, the catalyst was filtered by passing through a plug of Celite® and washing with additional ethanol. The filtrate was concentrated in vacuo and purified by preparative HPLC (Polaris C18-A 10 μ 250×21.2 mm column, 30% to 95% acetonitrile-0.1% trifluoroacetic acid in water) affording methyl 6-O-(4′-{(2S,3R)-1-(4-fluorophenyl)-3-[(3S)-3-(4-fluorophenyl)-3-hydroxypropyl]-4-oxoazetidin-2-yl}biphenyl-3-yl)-α-D-glucopyranoside (18.1 mg, 36% yield); 1H NMR (300 MHz, CDCl3/1% CD3OD) δ 7.58 (d, J=8.4 Hz, 2H), 7.38-7.23 (m, 7H), 7.17-7.14 (m, 2H), 7.04-6.92 (m, 5H), 4.80 (d, J=3.9 Hz, 1H), 4.70 (d, J=2.4 Hz, 1H), 4.67 (t, J=5.7 Hz, 1H), 4.37-4.33 (m, 1H), 4.26-4.21 (m, 1H), 3.92-3.87 (m, 1H), 3.74-3.45 (m, 3H), 3.42 (s, 3H), 3.18-3.10 (m, 1H), 2.01-1.88 (m, 4H) ppm; MS [M−OH]+ 644.0.
