YieldReaction ConditionsOperation in experiment
60% To a suspension of acetylated ganciclovir, 2 (0.382 g, 1.0 mmol) in dry THF (5.0 mL) were subsequently added under stirring triphenylphosphine (0.393 g, 1.5 mmol) and alcohol, 3 (0.616 g, 2.0 mmol) under nitrogen atmosphere. Initially, reaction mixture was not clear but after 15 min when diethyl azodicarboxylate (DEAD) (0.261 g, 1.5 mmol) in dry THF (2.0 mL) was added drop wise, the reaction mixture turned yellow and started to become clear. The reaction was continued to stir at 25° C. for 10 hours. THF was evaporated under reduced pressure and the crude reaction mixture was extracted with DCM (3×30 mL) from water. The combined organic layer was washed with brine and dried over anhydrous sodium sulphate, filtered and evaporated to get yellowish oil. The crude product loaded on silica gel column and purified by 2-4percent Methanol/Dichloromethane. Desired product, 4 was less polar than starting compound 2. The expected product was eluted in 3percent MeOH/DCM solvent system as a colorless oil (0.403 g, 0.6 mmol, yield 60percent). 1H NMR (400 MHz, CDCl3): delta 8.13 (S, 1H), 7.96 (s, 1H), 5.66 (s, 2H), 4.68 (t, J=3.5 Hz, 2H), 4.21-4.14 (m, 2H), 4.11-4.02 (m, 2H), 3.93 (t, J=3.0 Hz, 2H), 3.79-3.72 (m, 5H), 3.69-3.67 (m, 6H), 3.54 (t, J=3.0 Hz, 2H), 2.56 (s, 3H), 1.97 (s, 6H), 0.88 (s, 9H), 0.06 (s, 6H). 13C NMR (CDCl3, 100 MHz): delta 170.5, 161.0, 153.3, 152.5, 141.9, 117.4, 74.7, 72.6, 71.8, 70.8, 70.7, 70.66, 70.6, 68.9, 66.7, 62.9, 62.6, 25.9, 25.2, 20.6, ?5.2. ESI-LC/MS: Expected [M+H]+ for C29H49N5O11Si is 672.32, found m/z: 672.51 [M+H]+.
