  • Preparation of 4‘-Substituted Thymidines by Substitution of the Thymidine 5‘-Esters
    作者:Michael E. Jung、Akemi Toyota
    DOI:10.1021/jo001223a
    日期:2001.4.1
    coupling constant analysis of both the initial compounds and the diols 6bcd prepared by ester reduction and by formation of the acetonides 7bc. The methyl ester of the 3'-epimer of thymidylic acid 9 was also prepared from thymidine 1 in nine steps and 74% overall yield. When the lithium trianion of 9 (prepared by treatment of 9 with excess LDA and then excess tert-butyllithum) is reacted with electrophiles
    由胸腺嘧啶核苷1分六步制备胸腺嘧啶叔丁酯3,总产率为67%。当3的三价锂离子(通过用过量的LDA处理3,然后用过量的叔丁基锂处理)与亲电试剂反应时,取决于亲电试剂,会从α面或β面立体选择性地发生捕集(方案1)。氘代甲醇中的氘代乙酸主要提供α-氘代产物(4a / 4b = 2.4:1),而所有其他亲电试剂,例如苯硒基氯,烯丙基溴和N-氟苯磺酰亚胺(NFSI),则主要(或完全)产生从beta脸攻击(5bcd / 4bcd = 3.7:1到100:0)。通过对初始化合物和通过酯还原制得的丙酮化物7bc形成的二醇6bcd的偶合常数分析,来确定产物的结构。胸苷酸9的3'-末端的甲酯也由胸腺嘧啶核苷1分九步制备,总产率为74%。当9的三价锂离子(通过用过量的LDA然后用过量的叔丁基锂处理9制备)与亲电试剂反应时,也会根据亲电试剂选择性地发生俘获,从而对α-或β面产生立体选择性的捕集(方案2) 。同样,
  • A practical synthesis of benzyl esters and related derivatives
    作者:Mélanie Fauré-Tromeur、Samir Z Zard
    DOI:10.1016/s0040-4039(98)01563-9
    日期:1998.10
    Heating carboxylic acids with O-benzyl-S-propargyl xanthate in refluxing toluene gives the corresponding benzyl esters in high yield; other acidic substances such as tetrazoles and pyridinols are benzylated selectively under the same conditions.
    在回流的甲苯中,将羧酸与O-苄基-S-炔丙基黄原酸酯一起加热,得到相应的苄基酯,收率很高。在相同条件下,其他酸性物质(如四唑和吡啶醇)被选择性地苄基化。
  • Stereocontrolled radical reactions in carbohydrate and nucleoside chemistry.
    作者:Derek H.R. Barton、Stephane D. Géro、Béatrice Quiclet-Sire、Mohammad Samadi
    DOI:10.1016/s0957-4166(00)86288-6
    日期:1994.11
    The radicals, generated by photolysis of 2,3-dimethyl ketals of N-hydroxy-2- thiopyridone uronic esters, reacted stereoselectively with electron deficient olefins leading to highly functionalised chain-elongated pentafuranosides, hexapyranosides and pentafuranosyl-nucleosides through the 4,5 and 4' radicals, respectively.
  • Total Synthesis of the Thymidine Analogue of Sinefungin
    作者:Derek H. R. Barton、Stephan D. Gero、Guillerm Negron、Béatrice Quiclet-Sire、Mohammad Samadi、Claire Vincent
    DOI:10.1080/15257779508009744
    日期:1995.10
    The carbon skeleton of ''Sinethymidin'' 4 was constructed by two radical coupling reaction. The first step was a coupling of the radical derived from 2 and the unsaturated amide 5. The olefin 6 thus obtained was added to the radical derived from the known N-hydroxy-2-thiopyridinone aspartic ester. ''Sinethymidin'', tested for its antileismanial effect, was devoid of activity.
  • Replacement of the phosphodiester linkage in oligonucleotides by an amide: Effect of backbone length on duplex stability with RNA complement
    作者:Alain De Mesmaeker、Chantal Jouanno、Romain M. Wolf、Sebastian Wendeborn
    DOI:10.1016/s0960-894x(97)00037-1
    日期:1997.2
    Five dimers containing amide linkages instead of the natural phosphodiester linkage were synthesized and incorporated into oligonucleotides. The length of the amide backbone was varied. The hybridization properties of the modified oligonucleotides with RNA complements and their conformational analysis are described and compared to previously reported amide containing oligonucleotides. In addition, the synthesis of a thioamide phosphoramidite dimer is reported. (C) 1997, Elsevier Science Ltd.
