4-d]pyrimidine (6b) with the halogenose 7 was achieved by employing phase-transfer techniques. The N-1 glycosylation product 3a was formed in preponderance. It was converted into the allopurinol β-D-2′-deoxyribonucleoside 2.
通过使用相转移技术,实现了4-甲氧基-1H-
吡唑并[3,4-d]
嘧啶(6b)与卤代糖7的区域选择性糖基化。N-1糖基化产物3a大量形成。将其转化为别
嘌呤醇β-D-2'-脱氧
核糖核苷2。
