We report a four-step synthesis of 2′-deoxy-2-deuteroadenosine from 2′-deoxyadenosine in 38% overall yield. The more accessible 2′-deoxy-8-deuteroadenosine was also prepared and incorporated into DNA by automated solid phase synthesis (80% deuterium) using N 6-benzoyl-2′-deoxy-8-deuteroadenosine-3′-O-(2-cyanoethyl-N,N-diisopropylphosphoramidite) in combination with acetyl-protected deoxycytidine and
我们报告了从 2'-脱氧腺苷以 38% 的总产率四步合成 2'-脱氧-2-deuteroadenosine。使用 N 6-benzoyl-2'-deoxy-8-deuteroadenosine-3'-O-(2 -氰乙基-N,N-二异丙基亚磷酰胺)与乙酰基保护的脱氧胞苷和苯氧基乙酰基保护的嘌呤亚磷酰胺组合。

Intramolecular asymmetric carbopalladation of N-aryl acrylamides followed by intermolecular trapping of the resulting σ-C(sp(3))-Pd complex by azoles afforded 3,3-disubstituted oxindoles in good yields with excellent enantioselectivities. Two C-C bonds were created with concurrent formation of an all-carbon quaternary stereocenter. Oxadiazole substituted oxindoles were subsequently converted to pyrroloindolines
N-芳基丙烯酰胺的分子内不对称碳钯化,然后用唑类分子间捕获所得的 σ-C(sp(3))-Pd 复合物,以良好的收率和出色的对映选择性提供了 3,3-二取代的羟吲哚。创建了两个 CC 键,同时形成了一个全碳四元立体中心。恶二唑取代的羟吲哚随后通过前所未有的还原环化方案转化为吡咯并二氢吲哚。(+)-esermethole 的对映选择性合成说明了这种化学的效用。

Iterative structure–activity analyses in a class of highly functionalized furo[2,3-b]pyridines led to the identification of the second generation pan-genotypic hepatitis C virus NS5Bpolymerase primer grip inhibitor BMT-052 (14), a potential clinical candidate. The key challenge of poor metabolic stability was overcome by strategic incorporation of deuterium at potential metabolic soft spots. The preclinical
对一类高度功能化的呋喃[2,3- b ]吡啶类化合物进行的迭代结构-活性分析导致鉴定出第二代泛基因型丙型肝炎病毒NS5B聚合酶引物抓地力抑制剂BMT-052(14) 。通过在潜在的代谢软斑处战略性地掺入氘,克服了不良的代谢稳定性的关键挑战。描述了BMT-052(14)的临床前概况和状态。
A newly devised method for the oxidative unmasking of 1,N6-ethenoadenosines: Facile conversion of adenosine into 2-deuterated adenosine.
2-Deuterated adenosine (5) was conveniently prepared from adenosine (1) by applying the ring-fission and reclosure methodology of 1, N6-ethenoadenosine (2) and a new oxidative unmasking method of the etheno moiety.
