  Synthesis of (Z)-(2,3-bis-Hydroxymethyl)methylenecyclopropane Analogues of Purine Nucleosides

  摘要：

  Synthesis of (Z)-(2,3-bis-hydroxymethyl)methylenecyclopropane analogues of nucleosides adenosine 10a, 10b, 10c and 17 is described. Epimerization of Feist's acid (11) using acetic anhydride gave cyclic anhydride 12 which was reduced in situ to give diol 13. Acetylation (compound 14) followed by addition of bromine led to dibromo derivative 15. Alkylation-elimination of adenine with 15 afforded, after deacetylation, analogue 10a. Similar treatment of 2-amino-6-chloropurine and 2,6-diaminopurine led to diacetates 16 and 18. Deprotection then gave compounds 17 and 10c. Hydrolysis of 17 furnished guanine analogue 10b. Compounds 10a, l0b or 10c were inactive against HCMV, HSV-1, HSV-2, EBV, VZV and HBV. Analogues 10a and 10b were also assayed for anti-HIV activity. Compound 10a was effective in HIV-1/MT-2 culture with EC50/CC50 33/> 100 muM but 10b was inactive. Analogue 10a was not a substrate for adenosine deaminase.

  Abstract Starting from a chiral methylenecyclopropane building block, readily obtained by enzymatic desymmetrization of a meso-diol, two types of methylenecyclopropane analogues of nucleosides were synthesized. The first type of nucleosides was obtained from the direct coupling of the chiral building block with 6-chloropurine under Mitsunobu reaction conditions followed by the functionalization of

  摘要 从手性亚甲基环丙烷结构单元开始，该结构单元是通过内消旋二醇的酶促脱对称反应容易获得的，合成了两种类型的核苷亚甲基环丙烷类似物。第一类核苷是通过在Mitsunobu反应条件下将手性结构单元与6-氯嘌呤直接偶联，然后将嘌呤碱官能化而获得的。第二种核苷以库尔修斯重排为关键步骤，然后通过线性方法构建尿嘧啶杂环。这些衍生物被评估为对抗重要病毒病原体的潜在药物。新化合物在100μg/ mL的浓度下均无明显的抗病毒活性，这是测试的最高浓度。 从手性亚甲基环丙烷结构单元开始，该结构单元是通过内消旋二醇的酶促脱对称反应容易获得的，合成了两种类型的核苷亚甲基环丙烷类似物。第一类核苷是通过在Mitsunobu反应条件下将手性结构单元与6-氯嘌呤直接偶联，然后将嘌呤碱官能化而获得的。第二种核苷以库尔修斯重排为关键步骤，然后通过线性方法构建尿嘧啶杂环。这些衍生物被评估为对抗重要病毒病原体的潜在药物。新化合物在100μg/

  The enzymatic desymmetrization of methylenecyclopropane diol or its corresponding diacetate derivative, generated from a [2+1] cycloaddition between dioxepin and methylchlorocarbene, is described. After screening five commercial lipases, the two enantiomers of acetic acid 2-hydroxymethyl-3-methylene-cyclopropylmethyl ester are obtained in high yields and excellent enantioselectivities by using PFL

  描述了亚甲基环丙烷二醇或其相应的二乙酸酯衍生物的酶促脱对称，该二甲基环氧丙烷是由二氧杂环庚烷和甲基氯卡宾之间的[2 + 1]环加成反应生成的。在筛选出五种商业脂肪酶后，通过在有机溶剂中使用PFL或LPP，可以高收率和优异的对映选择性获得乙酸2-羟基甲基-3-亚甲基-环丙基甲基酯的两种对映体。通过X射线分析建立了去对称产物的立体结构。我们还报道了这种非外消旋手性结构单元的新例子，其中旋光的迹象显着取决于溶剂并被反转。使用这些对映体纯的组成部分，还提出了新型核苷类似物的合成。
