  摘要：

  A series of tricyclic quinoxalinediones, 5,6-dihydro-1H-pyrrolo[1,2,3-de]quinoxaline-2,3-diones and 6,7-dihydro-1H,5H-pyrido[1,2,3-de]quinoxaline-2,3-diones, were synthesized and was evaluated for their affinity for the glycine binding site of the NMDA receptor using a [H-3]- 5,7-dichlorokynurenic acid binding assay. The six-membered ring-fused tricyclic quinoxalinedione 18g (K-i = 9.9 nM) displayed high affinity for the glycine site. The anilide derivative 20g (K-i = 2.6 nM) was 4-fold more potent than 18g and as potent as L-689,560, one of the most potent glycine antagonists so far prepared. Although the carboxylic acid derivative of the corresponding five-membered ring-fused tricyclic quinoxalinedione 18e (K-i = 7.3 nM) had affinity comparable to that of 18g, the anilide derivative 20e largely decreased in the affinity in contrast to 20g. Enantiomers 23g, 24g, 25g, and 26g were prepared and tested. Only the S enantiomer 25g (K-i = 0.96 nM) retained the affinity among the anilide derivatives, whereas both enantiomers 23g (K-i = 2.3 nM) and 24g (K-i = 9.6 nM) were active among the carboxylic acid derivatives. The origin of the high affinity of carboxylic acid derivatives such as 18e and 18g would be a charge-charge interaction between the anionic carboxylate residues of the compounds and the cationic proton-donor site in the receptor.

• Highly Enantioselective Iridium-Catalyzed Hydrogenation of 2-Benzylquinolines and 2-Functionalized and 2,3-Disubstituted Quinolines

  The enantioselective hydrogenation of 2-benzylquinolines and 2-functionalized and 2,3-disubstituted quinolines was developed by using the [Ir(COD)Cl]2/bisphosphine/I2 system with up to 96% ee. Moreover, mechanistic studies revealed the hydrogenation mechanism of quinoline involves a 1,4-hydride addition, isomerization, and 1,2-hydride addition, and the catalytic active species may be a Ir(III) complex

  Helical chirality and selective anion-binding processes are key strategies used in nature to promote highly enantioselective chemical reactions. Although enormous efforts have been made to develop simple helical chiral systems and thus open new possibilities in asymmetric catalysis and synthesis, the efficient use of synthetic oligo- and polymeric helical chiral catalysts is still very challenging

  螺旋手性和选择性阴离子结合过程是自然界中用于促进高度对映选择性化学反应的关键策略。尽管已经为开发简单的螺旋手性体系做出了巨大的努力，从而为不对称催化和合成开辟了新的可能性，但合成低聚和聚合螺旋手性催化剂的有效使用仍然非常具有挑战性且相当不寻常。在这项工作中，结构独特的手性低聚三唑已被开发作为基于 CH 键的阴离子结合催化剂，用于 N-杂芳烃的不对称脱芳构化。这些旋转柔性催化剂在与氯阴离子结合时采用增强的手性螺旋构象，允许通过与预先形成的离子底物的紧密手性阴离子对复合物进行高水平的手性转移。
