    摘要:
    在室温下,使用催化量的溴二甲基溴化锍(0.005-0.02 当量)可以将各种醇和酚有效地转化为相应的四氢吡喃 (THP) 醚,产率很高。另一方面,通过使用 0.05 当量的相同催化剂,各种 THP 醚也可以在 CH2Cl2/MeOH (5:2) 中脱保护为母体醇或酚化合物。该方法的一些主要优点是条件温和,选择性和效率高,收率高,成本效益高,不需要溶剂,并且与其他保护基团的存在相容。此外,在双键或三键、烯丙基位置或什至在芳环上都不会发生溴化。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)

    Selective alkylation of pyrimidyl dianions II: synthesis, characterization, and comparative reactivity of 3′, 5′-o-bis- tetrahydropyranyl, trimethylsilyl and tert-butyldimethylsilyl derivatives of 5-bromo-2′-deoxyuridine
    摘要:
    Three compounds which can be used as precursors for thymidine synthesis via methylation at the 5 position, including 3', 5'-o-bis(tetrahydropyranyl)-5-bromo-2'-deoxyuridine 1a, 3', 5'-o-bis-(trimethylsily)-5-bromo-2'-deoxyuridine 1b, and 3', 5'-o-bis-(t-butyldimethylsilyl)-5-bromo-2'-deoxyuridine 1c, were prepared isolated and characterized by spectroscopic methods. Alkylation with methyl iodide using an organo-lithium reagent at low temperature produced 72%, 41% and 74% of thymidine 6, respectively. Tetrahydropyranyl and t-butyldimethylsilyl ethers are found to be better precursors for introduction of a methyl group at the 5 position.

  • Synthesis of [18F]-labeled N-3(substituted) thymidine analogues: N-3([18F]fluorobutyl) thymidine ([18F]-FBT) and N-3([18F]fluoropentyl) thymidine ([18F]-FPT) for PET

    Syntheses of N-3(substituted) analogues of thymidine, N-3([18F]fluorobutyl)thymidine ([18F]-FBT) and N-3([18F]fluoropentyl)thymidine ([18F]-FPT) are reported. 1,4-Butane diol and 1,5 pentane diol were converted to their tosyl derivatives 2 and 3 followed by conversion to benzoate esters 4 and 5, respectively. Protected thymidine 1 was coupled separately with 4 and 5 to produce 6 and 7, which were hydrolyzed to 8 and 9, then converted to their mesylates 10 and 11, respectively. Compounds 10 and 11 were fluorinated with n-Bu4N[18F] to produce 12 and 13, which by acid hydrolysis yielded 14 and 15, respectively. The crude products were purified by HPLC to obtain [18F]-FBT and [18F]-FPT. The radiochemical yields were 58–65% decay corrected (d.c.) for 14 and 46–57% (d.c.) for 15 with an average of 56% in three runs per compound. Radiochemical purity was >99% and specific activity was >74 GBq/µmol at the end of synthesis (EOS). The synthesis time was 65–75 min from the end of bombardment (EOB).

    Radiosyntheses of two N3-substituted thymidine analogues, N3-[(4[18F]fluoromethyl-phenyl)butyl]thymidine ([18F]-FMPBT) and N3-[(4[18F]fluoromethyl-phenyl)pentyl]thymidine ([18F]-FMPPT), are reported. The precursor compounds 9 and 10 were synthesized in six steps and the standard compounds 13 and 14 were synthesized from these precursors. For radiosynthesis, compounds 9 and 10 were fluorinated with n-Bu4N[18F] to produce [18F]-11 and [18F]-12, which by acid hydrolysis yielded [18F]-13 and [18F]-14, respectively. The crude products were purified by high-performance liquid chromatography to obtain [18F]-FMPBT and [18F]-FMPPT. The average decay-corrected radiochemical yield for [18F]-13 was 15% in five runs, and that for [18F]-14 was 10% in four runs. The radiochemical purity was >99% and the specific activity was >74 GBq/µmol at the end of synthesis. The synthesis time was 80–90 min from the end of bombardment.

    Various alcohols and phenols can be converted efficiently to the corresponding tetrahydropyranyl (THP) ethers in good yields using catalytic amounts of bromodimethylsulfonium bromide (0.005−0.02 equivalent) at room temperature. On the other hand, various THP ethers can also be deprotected to the parent alcoholic or phenolic compounds in CH2Cl2/MeOH (5:2) by employing 0.05 equivalent of the same catalyst
