室温条件利用β-环糊精作为助剂,通过亲核取代反应在水相中合成了一系列9-(2,3-环氧丙基)嘌呤核苷。本方法操作简单,反应条件温和,收率较高。β-CD的作用在于通过与底物包结增加它们在水中的溶解度,减少副反应发生,促进反应进行。
9-Glycidyl purine nucleosides were synthesized through nucleophilic substitution reaction under mild reaction conditions assisted by β-CD in water. The role of β-CD was that it included purine ring to increase the solubility of the substrates and to pro-mote the reaction.
