  A process for providing regiospecific and highly stereoselective synthesis of 9-β anomeric purine nucleoside analogs is described. The introduction of the sugar moiety on to 6-(azolyl)-substituted purine bases is performed so that highly stereoselective formation of the β anomers of only the 9 position regioisomers of the purine nucleoside analogs (either D or L enantiomers) is obtained. This regiospecific and stereoselective introduction of the sugar moiety allows the synthesis of nucleoside analogs, and in particular 2′-deoxy, 3′-deoxy, 2′-deoxy-2′-halo-arabino and 2′,3′-dideoxy-2′-halo-threo purine nucleoside analogs, in high yields without formation of the 7-positional regioisomers. Processes for providing novel 6-(azolyl)purines for the regiospecific and highly stereoselective synthesis of 9-β anomeric purine nucleoside analogs are described. The compounds are drugs or intermediates to drugs.

  本文描述了一种提供9-β异构嘌呤核苷类似物的区域特异性和高度立体选择性合成的方法。将糖基引入到6-(咪唑基)-取代的嘌呤碱基上，以获得嘌呤核苷类似物的β异构体的高度立体选择性形成（D或L对映体）。这种区域特异性和立体选择性引入糖基的方法，允许高产率地合成核苷类似物，特别是2'-去氧、3'-去氧、2'-去氧-2'-卤代阿拉伯糖和2',3'-二去氧-2'-卤代-threo嘌呤核苷类似物，而不形成7位异构体。本文还描述了提供新型6-(咪唑基)嘌呤用于区域特异性和高度立体选择性合成9-β异构嘌呤核苷类似物的方法。这些化合物是药物或药物中间体。
