text]. A stereselective synthesis of 3-oxabicyclo[3.2.0]heptane nucleoside analogues, which were designed as conformational mimics of the anti-HIV agents 2',3'-didehydro-2',3'-dideoxythimidine (stavudine, d4T) and 2',3'-didehydro-2',3'-dideoxyadenosine (d4A), is described. The target compounds were prepared by condensation of a common intermediate bicyclic acetate, derived from a homochiral 2(5H)-furanone
[结构:见文字]。立体选择性合成3-氧杂双环[3.2.0]庚烷核苷类似物,其被设计为抗HIV药物2',3'-didehydro-2',3'-dideoxythimidine(stavudine,d4T)和2的构象模拟物描述了',3'-二氢化-2',3'-二脱氧腺苷(d4A)。通过在改良的Vorbruggen条件下,将衍生自同手性2(5H)-呋喃酮的常见中间体双环乙酸酯与嘧啶和嘌呤碱缩合,制得目标化合物。合成核苷类似物的构象行为通过NMR光谱和X射线晶体学研究。
