[reaction: see text] A new method for the synthesis of 2',3'-dideoxynucleoside analogues has been developed. An electrochemical activation of 2-substituted furans is followed by the coupling with a pyrimidine or purine base. This gives planar furyl nucleosides as key intermediates, which are hydrogenated cis-selectively to give the corresponding beta-2',3'-dideoxynucleosides as racemic mixtures. An enzymatic
[反应:见正文]已开发出一种合成2',3'-二脱氧核苷类似物的新方法。2-取代的呋喃的电化学活化后,与嘧啶或嘌呤碱偶联。这得到平面的呋喃基核苷作为关键中间体,顺式-选择性地氢化得到相应的β-2',3'-二脱氧核苷作为外消旋混合物。酶促动力学拆分产生具有高光学纯度的β-D-和β-L-构型的衍生物。以β-D-和β-L-3'-脱氧胸苷的合成为例。
