  Aryl and cycloalkyl analogues of AMPA: synthetic, pharmacological and stereochemical aspects

  摘要：

  We have previously shown that (RS)-2-amino-3-(3-hydroxy-5-phenylisoxazol-4-yl)propionic acid (APPA, 2) is a functional partial agonist at the (RS)-2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propionic acid (AMPA) subtype of excitatory amino acid receptors, reflecting that (S)-APPA is a full agonist and (R)-APPA a competitive antagonist at AMPA receptors. We have now synthesized and pharmacologically characterized (RS)-2-amino-3-[3-hydroxy-5-(2-fluorophenyl)isoxazol-4-yl]propionic acid (2-F-APPA, 5a), 3-F-APPA (5b), 4-F-APPA (5c), (S)-4-F-APPA (6), (R)-4-F-APPA (7), and the fully and partially, respectively, saturated APPA (2) analogues, (RS)-2-amino-3-(3-hydroxy-5-cyclohexylisoxazol-4-yl)propionic acid (5d) and compound 5e containing a 1-cyclohexenyl ring. The absolute stereochemistry of 6 and 7 was established on the basis of comparative circular dichroism studies on 6, 7, and (S)- and (R)-APPA. 4-F-APPA (5c), (S)-4-F-APPA (6), 5d, and 5e were shown to selectively inhibit [H-3]AMPA binding and to activate AMPA receptors. Whereas (S)-4-F-APPA (6) showed full AMPA receptor agonism, (R)-4-F-APPA (7) was an AMPA receptor antagonist. Co-administration of (S)- and (R)-4-F-APPA to the rat cortical wedge preparation produced functional partial AMPA receptor agonism. Semi empirical calculations showed that the magnitude of the torsional angle of the bond connecting the two rings in the series of nonannulated bicyclic AMPA analogues appears to be of importance for the potency and efficacy of these compounds.

  Michael受体与通过铑催化的C–C键活化产生的芳基亲核试剂的氧化偶联

  摘要：

  利用铑催化，通过碳-碳单键活化产生的芳基亲核试剂成功地与迈克尔受体进行了氧化偶联。反应范围涵盖了由喹啉基酮以及一系列电子不足的末端烯烃产生的亲核试剂，说明了碳-碳键活化与合成有用的偶联方法相交的广阔潜力。证明的氧化偶合产生了一系列肉桂基衍生物，其中一些是难以通过常规途径制备的。

  Mizoroki–Heck reaction of unstrained aryl ketone with acrylate/styrene is accomplished via palladium-catalyzed ligand-promoted C–C bond cleavage. Various (hetero)aryl ketones are compatible in the reaction, affording the alkene product in good to excellent yields. Further applications in the late-stage olefination of some drugs, natural products, and fragrance-derived aryl ketones demonstrate the synthetic utility

  未应变的芳基酮与丙烯酸酯/苯乙烯的Mizoroki-Heck反应是通过钯催化的配体促进的C-C键裂解实现的。各种（杂）芳基酮在反应中是相容的，从而以良好至优异的产率提供了烯烃产物。在某些药物，天然产物和香料衍生的芳基酮的后期烯烃聚合中的进一步应用证明了该方案的合成效用。通过采用酮作为导向基团和离去基团二者，1,2- bifunctionalization经由顺序实现邻-C-H的烷基化/本位-Heck烯。

  Direct α‐functionalization of NH2‐free glycinates with relatively weak electrophiles such as α,β‐unsaturated esters still remains a big challenge in organic synthesis. With chiral pyridoxal 5 d as a carbonyl catalyst, direct asymmetric conjugated addition at the α‐C of glycinate 1 a with α,β‐unsaturated esters 2 has been successfully realized, to produce various chiral pyroglutamic acid esters 4 in 14–96 %

  用相对较弱的亲电试剂（例如，α，β-不饱和酯）将不含NH 2的甘氨酸直接进行α-官能化仍然是有机合成中的一大挑战。以手性吡ido醛5 d作为羰基催化剂，已成功实现在甘氨酸1a的α-C与α，β-不饱和酯2的直接不对称共轭加成反应，以14-96％的收率生产各种手性焦谷氨酸酯4原位内酰胺化后具有81–97％ee的物质。该反式与顺非对映异构体可以通过色谱法同时获得，并且可以很容易地通过叔丁基去除和随后的Barton转化为手性4取代的吡咯烷-2-酮，例如具有相同绝对构型的阿兹海默氏药物Rolipram（11）。脱羧。
