  Effect of transition-metal complexation on the stereodynamics of persubstituted arenes. Evidence for steric complementarity between arene and metal tripod

  摘要：

  The stereodynamics in 1,4-dimethoxy-2,3,5,6-tetraethylbenzene (5), 1,4-bis(methoxymethyl)-2,3,5,6-tetraethylbenzene (6), and 1,4-dineohexyl-2,3,5,6-tetraethylbenzene (7) and their respective tricarbonylchromium complexes, 5(Cr), 6(Cr), and 7(Cr), have been studied by variable-temperature NMR techniques. Barriers to rotation about the sp2-sp3 bonds for 5-7 and 5(Cr)-7(Cr) have been determined using the Gutowsky-Holm approximation to be 7.7, 9.4, 11.2, 6.6, 8.9, and 11.8 kcal/mol, respectively. Unlike previous studies in this area, the stereodynamics of the arene do not change demonstrably upon metal complexation. This observation is attributed to a lock-and-key complementarity between the metal tripod and the arene. The possibility of correlated dynamics between the metal tripod rotation and the ethyl group rotation is discussed.

  Activation of the neuropeptide S receptor (NPSR) system has been shown to produce anxiolytic-like actions, arousal, and enhance memory consolidation, whereas blockade of the NPSR has been shown to reduce relapse to substances of abuse and duration of anesthetics. We report here the discovery of a novel core scaffold (+) N-benzyl-3-(2-methylpropyl)-1-oxo-3-phenyl-1H,3H,4H,5H,6H,7H-furo[3,4-c]pyridine-5-carboxamide with potent NPSR antagonist activity in vitro. Pharmacokinetic parameters demonstrate that 14b reaches pharmacologically relevant levels in plasma and the brain following intraperitoneal (i.p.) administration, but is cleared rapidly from plasma. Compound 14b was able to block NPS (0.3 nmol)-stimulated locomotor activity in C57/Bl6 mice at 3 mg/kg (i.p.), indicating potent in vivo activity for the structural class. This suggests that 14b can serve as a useful tool for continued mapping of the pharmacological functions of the NPS receptor system.

  激活神经肽S受体（NPSR）系统已被证明可以产生类似抗焦虑的作用、觉醒和提高记忆巩固，而阻断NPSR已被证明可以减少对滥用物质的复吸和麻醉剂的持续时间。我们在这里报告了一个新型核心支架（+）N-苄基-3-(2-甲基丙基)-1-氧代-3-苯基-1H,3H,4H,5H,6H,7H-呋喃[3,4-c]吡啶-5-甲酰胺的发现，该化合物在体外具有强大的NPSR拮抗活性。药代动力学参数表明，14b在腹腔注射（i.p.）后达到药理学相关水平，但会迅速从血浆中清除。化合物14b能够阻断C57/Bl6小鼠中由NPS（0.3纳米摩尔）刺激的移动活动，剂量为3毫克/千克（i.p.），表明该结构类别在体内具有强大的活性。这表明14b可以作为继续映射NPS受体系统药理功能的的有用工具。

  weak C−O bond. Spontaneous scission results in the formation of the stable nitroxyl radical TEMPO. as well as a reactive carbocation intermediate that can be intercepted by a wide range of nucleophiles. Notably, this process occurs under neutral conditions and at comparatively mild potentials, enabling catalytic cation generation in the presence of both acid sensitive and easily oxidized nucleophilic

  Iridium‐catalyzed enantioselective transfer hydrogenation of ketones with formic acid was developed using a prolinol‐phosphine chiral ligand. Cooperative action of the iridium atom and the ligand through alcohol‐alkoxide interconversion is crucial to facilitate the transfer hydrogenation. Various ketones including alkyl aryl ketones, ketoesters, and an aryl heteroaryl ketone were competent substrates
