  Allylsilanes in the preparation of 5′-C-hydroxy or bromo alkylthymidines

  摘要：

  The reaction of 5'-C-thymidine aldehyde with allytrimethylsilane promoted by BF3:Et2O lead stereoselectively to 5'-C(S)-allylthymidine which is converted to 5'-C(S) C(S)-hydroxyhexylthymidine. 5'-C-(R or S) hydroxypentylthymidine can be obtained by using omega-tertButyldimethylsilyloxyallyltrimethylsilane in the Sakurai reaction. In the same conditions, omega-Bromoallyltrimethylsilane adds to the aldehyde with a complete transposition of the siliranium intermediate and allows the preparation of the 5'-C(S)-bromopentene derivative, (C) 1999 Elsevier Science Ltd.

• Synthesis of Phostone-Constrained Nucleic Acid (P-CNA) Dinucleotides Through Intramolecular Arbuzov's Reaction

  P-CNAs are dinucleotide building blocks in which the torsional angles α and β of the sugar/phosphate backbone are constrained to non-canonical values within a cyclic phosphonate structure (phostone) synthesised by diastereoselective intramolecular Arbuzov reaction. The reaction has been improved through the use of microwave activation and addition of lithium bromide.

  P-CNA 是二核苷酸结构单元，其中糖/磷酸盐骨架的扭转角 α 和 β 被限制为非对映选择性分子内 Arbuzov 反应合成的环状膦酸酯结构（膦）内的非规范值。通过使用微波活化和添加溴化锂，该反应得到了改进。

  5'-C-substituted nucleosides with an hydroxyalkyl chain are synthesized. The stereochemistry of the new stereogenic center is defined. After introduction of a tosyl group, dimer models are prepared to evaluate the conjugation with amines used as nucleophiles.
