  Structure–affinity studies for a novel series of homochiral naphtho and tetrahydronaphtho analogues of α1 antagonist WB-4101

  摘要：

  A number of enantiomeric pairs of naphthodioxane, tetrahydronaphthodioxane and naphthoxy analogues of WB-4101 (1) were designed and synthesized in order to improve the selectivity profile of the parent compound, hopefully in favour of the alpha(1a)-AR with respect to the other two alpha(1), subtypes and the 5-HT1A receptor. The new compounds 2-8 and, in addition, the two enantiomers of 1 were tested in binding assays on the alpha(1a)-AR, alpha(1b)-AR, alpha(1d)-AR, and the 5-HT1A receptor. Two of them, namely the naphtho- and tetrahydronaphthodioxane derivatives (S)-2 and (S)-3, showed lower, but significantly more specific alpha(1a), affinity than (S)-1, while the two enantiomers of the 2-methoxy-1-naphthoxy analogue 6 maintained most of the very high alpha(1a) affinity of (S)-1 and its alpha(1a) versus alpha(1b) selectivity slightly increasing the alpha(1a)/alpha(1d) and alpha(1a)/5HT(1A) affinity ratios. The SAR data were evaluated in the light of known alpha(1), subtype pharmacophores and of the alpha(1a)-AR binding mode of WB-4101 resultant from literature mutagenesis studies disclosing some interesting consonances with these models.

  Synthesis and inhibitory evaluation of 3-linked imipramines for the exploration of the S2 site of the human serotonin transporter

  摘要：

  The human serotonin transporter is the primary target of several antidepressant drugs, and the importance of a primary, high affinity binding site (S1) for antidepressant binding is well documented. The existence of a lower affinity, secondary binding site (S2) has, however, been debated. Herein we report the synthesis of 3-position coupled imipramine ligands from clomipramine using a copper free Sonogashira reaction. Ligand design was inspired by results from docking and steered molecular dynamics simulations, and the ligands were utilized in a structure-activity relationship study of the positional relationship between the S1 and S2 sites. The computer simulations suggested that the S2 site does indeed exist although with lower affinity for imipramine than observed within the S1 site. Additionally, it was possible to dock the 3-linked imipramine analogs into positions which occupy the S1 and the S2 site simultaneously. The structure activity relationship study showed that the shortest ligands were the most potent, and mutations enlarging the proposed S2 site were found to affect the larger ligands positively, while the smaller ligands were mostly unaffected.

  α‐Functionalization of ketones in an umpolung fashion can be achieved by nucleophilic addition to the oxy‐allyl cation intermediate. However, applicable carbon nucleophiles are limited to ones with high nucleophilicity. Additionally, introduction of a leaving group to the α‐position of ketone substrates is required beforehand. Herein, we report the CuCl2‐mediated oxidative intramolecular α‐arylation

  酮的α-官能化可以通过亲核加成到氧基烯丙基阳离子中间体中来实现。但是，适用的碳亲核试剂限于亲核性高的亲核试剂。另外，事先需要在酮底物的α位上引入一个离去基团。在本文中，我们报告了通过酮的α-氯化作用以及随后生成的氧烯丙基阳离子中间体，将具有较少亲核酚类部分的酮的CuCl 2介导的氧化性α-芳基化为碳亲核体，得到了具有季碳中心的酮α位置。

  Aprotic solvents are usually preferred for the SN2 reactions, because nucleophilicity and hence SN2 reactivity are severely retarded by the influence of the partial positive charge of protic solvents. In this work, we introduce a remarkable effect of using tertiary alcohols as a reaction medium for nucleophilic fluorination with alkali metal fluorides. In this novel synthetic method, the nonpolar protic

  SN2 反应通常优选非质子溶剂，因为质子溶剂的部分正电荷的影响严重阻碍了亲核性和 SN2 反应性。在这项工作中，我们介绍了使用叔醇作为碱金属氟化物亲核氟化反应介质的显着效果。在这种新的合成方法中，非极性质子叔醇在没有任何催化剂的情况下显着增强了氟离子的亲核性，大大提高了亲核氟化的速率并减少了副产物（如烯烃、醇或醚）与使用偶极非质子溶剂的常规方法相比。
