  磺酰胺的催化sp3-sp3功能化：药物分子的后期修饰

  摘要：

  据报道，Pd催化的烯丙基化的新应用使得能够合成一系列支链的sp 3官能化的磺酰胺，这是报道的方法很少的化合物类别。在室温下，在Pd 0催化剂和碱的存在下，通过使苄基磺酰胺与烯丙基乙酸酯反应，可以有效地进行直接烯丙基化，生成的产物与具有生物活性的小分子中的结构图案类似。该反应在温和的条件下进行，可应用于纳摩尔的sigma-受体粘合剂，因此可实现后期功能化并有效扩展类药物的化学空间。

  Synthesis and receptor binding studies of novel 4,4-disubstituted arylalkyl/arylalkylsulfonyl piperazine and piperidine-based derivatives as a new class of σ1 ligands

  摘要：

  This study presents the synthesis and biological evaluation of a new series of arylalkyliary/alkylsulfonyl piperazine and piperidine-based derivatives as sigma receptor ligands. It was found that a number of halogen substituted sulfonamides display relatively high and low affinities to sigma(1) and sigma(2) receptors, respectively. The sigma(1) affinities and subtype selectivities of four piperidine derivatives were also found to be generally comparable to those of piperazine analogues. Compared to sigma(1)-Rs compounds with n = 0 and 2, those with n = 1 proved to have optimal length of carbon chain by exhibiting higher affinities.Within this series, the 4-benzyl-1-(3-iodobenzylsulfonyl)piperidine sigma ligand was identified with 96-fold sigma(1)/sigma(2) selectivity ratio (K-i sigma(i) = 0.96 +/- 0.05 nM and K-i sigma(2) = 91.8 +/- 8.1 nM).

  range of branched sp3‐functionalised sulfonamides, a compound class for which few reported methods exist. By reacting benzyl sulfonamides with allylic acetates in the presence of Pd0 catalysts and base at room temperature, direct allylation was efficiently performed, yielding products that are analogues of structural motifs seen in biologically active small molecules. The reaction was performed under
