  Design and Synthesis of New Naphthalenic Derivatives as Ligands for 2-[125I]Iodomelatonin Binding Sites

  摘要：

  New melatonin-like agents were designed from the frameworks of 2,5-dimethoxyphenethylamine, an important structural moiety for the 5-HT receptor, and (2-methoxynaphthyl)-ethylamine. The compounds were synthesized by classical methods and evaluated in binding assays with chicken brain membranes using 2-[I-125]iodomelatonin as the radioligand. Preliminary studies on the series of N-acyl-disubstituted phenethylamines showed the favorable role of the methoxy group in the ortho position of the side chain on the affinity for the receptor K-i = 8 +/- 0.2 nM) for N-[2-(2-methoxy-5-bromophenyl)ethyl]propionamide (3o). This effect was confirmed in a series of the naphthalene derivatives, a bioisosteric moiety of the indole ring, and several potent ligands for melatonin binding sites were prepared such as N-[2-(2-methoxynaphthyl)ethyl]propionamide (4b) (K-i = 0.67 +/- 0.05 nM) and N-[2-(2,7-dimethoxynaphthyl)ethyl]cyclopropylformamide (K-i = 0.05 +/- 0.004 nM) (4k). Structure-activity relationships are discussed with regard to melatonin and bioisosteric naphthalenic compound 2. The K-i value for 4b was affected to a similar extent to that of melatonin by GTP-gamma-S or Mn2+ in competition experiments, suggesting an agonist profile for this compound.

• Mechanistic study on iodine-catalyzed aromatic bromination of aryl ethers by N -Bromosuccinimide

  日期：2017.12

  Although iodine-catalyzed reaction has rapid advances in recent years, examples on iodine-catalyzed bromination are rare and the mechanism of these reactions remains unclear. Herein, we reported an I2-catalyzed aromatic bromination of aryl ethers by NBS and presented the details of the mechanistic study including kinetic study and the study of kinetic isotope effects. The study revealed that the reaction

  尽管近年来碘催化的反应发展迅速，但是碘催化溴化的例子很少，这些反应的机理尚不清楚。在本文中，我们报道了NBS的I 2催化的芳基醚的芳族溴化反应，并详细介绍了包括动力学研究和动力学同位素效应在内的机理研究。研究表明，该反应实际上是由诱导期形成的IBr催化的，而决定速率的步骤是在IBr辅助下消除Wheland中间体的HBr。

  A scalable cyanation of gem-difluoroalkenes to (hetero)arylacetonitrile derivatives was developed. This strategy features mild reaction conditions, excellent yields, wide substrate scope, and broad functional group tolerance. Significantly, in this reaction, aqueous ammonia offers a “N” source for the “CN” reagent and entirely avoids the use of toxic cyanating reagents or metal catalysis. Hence, we
