    We describe the synthesis of 2′-deoxy-3′,5′-ethano-D-ribonucleosides 1–8 (= (5′,8′-dihydroxy-2′-oxabicyclo-[3.3.0]oct-3′-yl)purines or -pyrimidines) of the nucleobases adenine, thymine, cytosine, and guanine. They differ from natural 2′-deoxyribonucleosides only by an additional ethylene bridge between the centers C(3′) and C(5′). The configuration at these centers (3S,5′R) was chosen as to match the
    我们描述了2'-deoxy-3',5'-ethano-D-ribonucleosides 1 – 8(=(5',8'-dihydroxy-2'-oxabicyclo- [3.3.0] oct-3'-核苷腺嘌呤,胸腺嘧啶胞嘧啶鸟嘌呤的基团)。它们与天然2'-脱氧核糖核苷的区别仅在于中心C(3')和C(5')之间有一个附加的乙烯桥。选择这些中心处的构型(3 S,5'R),以使其与双链DNA中重复的核苷单元的几何形状尽可能接近。这些核苷被设计为赋予作为寡核苷酸链的成分的相对于天然DNA较高的单链预组织度,以形成双链体,从而形成熵配对过程的优势。这些“bicyclonucleosides”的合成是通过结构的对映体纯糖前体的实现18 / 19(方案1),然后将其通过在核苷合成(已知的方法转化为相应的核苷方案2和3)。在所有情况下,两种核苷的端基异构体均以纯结晶形式获得,其相对构型通过1 H-NM

    A series of polyhydroxylated bicyclic nucleoside derivatives is approached applying stereoselective dihydroxylation reactions. Three out of four isomeric and protected products were obtained after the stereoselectivity of dihydroxylation has been completely inverted comparing a bicyclic nucleoside with a tricyclic furanose substrate. A corresponding 2′-deoxynucleoside derivative has been obtained after an optimized deoxygenation procedure.

    relative to the natural system. (ii) bcd(A10) discriminates between a complementary oligodeoxynucleotide with a mismatch in the center in the same way as d(A10), indicating equal base-pairing selectivity. (iii) bcd(A10) forms more stable triplexes with d(T10) of the pyrimidine-purine-pyrimidine (py · pu · py) motif than d(A10). (iv) The stability of duplexes containing a bicyclic strand is more sensitive
    描述了一种新型寡核苷酸('bicyclooligodeoxynucleotide'= bcd(X n))的合成,该寡核苷酸在其糖-磷酸骨架中显示出较小的构象柔性,并描述了十聚体bcd(T 10)和给出了bcd(A 10)相互之间以及通过紫外光谱和量热技术获得的互补RNA和DNA序列。结果可总结如下:(i)bcd(T 10)与互补的RNA和DNA的配对较弱,而bcd(A 10)相对于天然系统形成更强的双链体。(ii)bcd(A 10)以与d(A 10)相同的方式区分中心错配的互补寡聚脱氧核苷酸,表明碱基配对选择性相等。(III)BCD(A 10)形成与d更稳定的三螺旋(T 10嘧啶-嘌呤-嘧啶)(吡啶·プ·PY)基序比d(A 10)。(iv)含双环链的双链体的稳定性对盐浓度更敏感。包含bcd(A 10)的双链体具有较高的灵敏度,这是由于较高的差异阳离子摄取引起的。(v)双相形成焓的差示扫描量热法(DSC)分析显示ΔH
