Sodium naphthalenide effects removal of 2′-, 3′-, or 5′-O-tosyl groups from the sugar, and 2-, 6-, or 8-halogens from purine nucleosides. An improved tosyl protection strategy was developed for the synthesis of 9-(3-deoxy-3-fluoro-β-D-xylofuranosyl)adenine from 2′,5′-di-O-tosyladenosine.
萘二甲酸钠可去除糖中的2 '-,3'-或5'- O-甲苯磺酰基,并去除嘌呤核苷中的2-,6-或8-卤素。开发了一种改进的甲苯磺酰基保护策略,用于从2',5'-二-O-甲苯磺酰基腺苷合成9-(3-脱氧-3-氟-β-D-木呋喃糖基)腺嘌呤。
