  • C-1′ Radical-Based Approaches for the Synthesis of Anomeric Spironucleosides
    作者:Chryssostomos Chatgilialoglu、Thanasis Gimisis、Gian Piero Spada
    DOI:10.1002/(sici)1521-3765(19991001)5:10<2866::aid-chem2866>3.0.co;2-6

  • Synthesis of Anomeric Spiro Uracil Nucleosides with an Orthoester Structure: Stereoselective Cyclization Controlled by the C6-Substituent
    作者:Atsushi Kittaka、Hiromichi Tanaka、Hajime Kato、Yumiko Nonaka、Kazuo T Nakamura、Tadashi Miyasaka
    DOI:10.1016/s0040-4039(97)01486-x
    日期:1997.9
    Uracil nucleosides having an anomeric orthoester structure were synthesized fi om 2'-deoxy-6-(hydroxyalkyl)uridines through hypoiodite-initiated cyclization. The hydroxyalkyl substituent at the 6-position was found to control the anomeric stereochemistry (beta/alpha=7/1 similar to 1/46) of the cyclization. The transition state geometry of the reaction was postulated based on the X-ray crystallographic structure of the cyclized product 7 alpha to elucidate the observed stereoselectivity.

  • A new class of anomeric spironucleosides
    作者:Thanasis Gimisis、Chryssostomos Chatgilialoglu、Thanasis Gimisis、Carlo Castellari
    DOI:10.1039/a705742c
    日期:——
    A 1,5-hydrogen migration of a conveniently situated alkoxyl radical affords spironucleosides which possess an unusual orthoamide structure at the anomeric position; X-ray crystallography establishes the configuration of the C-1′ position.

    Synthesis of novel spiro uracil nucleosides with an anomeric orthoester structure in a stereoselective manner under the hypoio dite reaction conditions of Heusler-Kalvoda and Suárez is fully described. While 2′-deoxy-6-(hydroxymethyl)uridine 2 and 2′-deoxy-6-[(1-hydroxy-1-methyl)ethyl]uridine 4 gave β- and α-spiro nucleosides in 43–68% yields with low selectivity (), the secondary ary alcohols 3a and
    充分描述了在Heusler-Kalvoda和Suárez的低碘反应条件下以立体选择性方式合成具有异头酯原酸酯结构的新型螺尿嘧啶核苷。2'-deoxy-6-(羟甲基)尿苷2和2'-deoxy-6-[(1-羟基-1-甲基)乙基]尿苷4以43-68%的产率得到β-和α-螺代核苷,由于低选择性(),仲醇3a和3b的化学产率为68–79%,选择性明显好于()。在该6-(羟基)尿苷同行的方向6-8,16-17,和19似乎不仅受2'-取代基的控制,而且受C6-侧链的C7-立体中心的手性的控制,就像在2'-脱氧尿苷系列中一样。该反应的过渡态的几何形状被假定基于环化产物的X射线晶体结构20 α和24 β。
