A set of derivatives of cyclopentaneacetic acid cis-substituted at position 3 by nucleoside bases (both purines and pyrimidines) were prepared and characterized (see 11, 14, and 23a, b;Schemes 2–4). These molecules are carbocyclic analogs of 2′,3′-dideoxy-5′-homonucleosides. In this synthesis, the skeleton was constructed from norbornanone and a novel method based on Mitsunobu chemistry used for the
一组环戊烷乙酸衍生物的顺式在由核苷碱基位置3 -取代的(包括嘌呤和嘧啶)中制备和表征(参见11,14,和23A,B;方案2-4)。这些分子是2',3'-二脱氧-5'-同核苷的碳环类似物。在这种合成中,骨架是由降冰片烷酮和基于Mitsunobu化学的新方法用于引入核苷碱基取代基而构建的。这种方法的范围,进一步探索了通过双脱氧的环丁基类似物的制备(参见17,方案3)。
