Participants

Reaction Steps

Sodium formate (1.2 g) was added to a mixture of compound 24 (1.02 g, 0.52 mmol) and Pd/C (10%, 0.5 g) in methanol (20 mL). The mixture was refluxed for 20 min, cooled to room temperature and diluted with dichloromethane (20 mL). The catalyst was filtered off and the filtrate was concentrated under reduced pressure to give a white solid material, which was crystallised from 50% ethanol/water to yield 680 mg (77%) of compound 25. δH (DMSO-d6) 8.12, (1H, s 8-H), 8.09 (1H, s, 2-H), 7.43-7.24 (m, 9H, DMT), 6.90 (m, 4H, DMT), 5.97 (1H, s, 1′-H), 4.44 (1H, s, 2′-H), 4.33 (1H, s, 3′-H), 3.97 (1H, d, J 7.5, Bn), 3.91(1H, d, J 7.7), 3.74 (6H, s, DMT), 3.55 (1H, d, J 10.6). δc (DMSO-d6) 158.2, 156.6, 147.3, 146.1, 144.8, 137.1, 135.5, 135.3, 129.8, 127.9, 127.7, 126.8, 124.6, 113.3(DMT, hypoxantine), 87.1, 85.6, 79.3, 71.8, 70.5, 59.9 (ribose), 55.1 (DMT).
