  Synthesis of Quinolines from N-Tosyl-1-azadienes

  摘要：

  A route to aryl-substituted quinolines from N-tosyl 1-azadienes is described. The key steps are a [4+2] cycloaddition with benzyne followed by base treatment of the 1,4-dihydroquinoline product. The N-tosyl 1-azadienes were prepared from readily accessible cinnamaldehyde and chalcone substrates by condensation with p-TsNH2. Supplemental materials are available for this article.

  Synthesis and Evaluation of a Series of 3,4,5-Trimethoxycinnamic Acid Derivatives as Potential Antinarcotic Agents

  摘要：

  A series of 3,4,5‐trimethoxycinnamic acid derivatives was prepared and evaluated for antinarcotic effects on morphine dependence in mice and binding affinities on serotonergic receptors. The key synthetic strategies involve generation of ketones 6–7, esters 9–12 through condensation reaction, and amides 13–19 via coupling reaction using 1‐hydroxybenzotriazole/ethyl(dimethylaminopropryl)carbodiimide system in high yield. We found that the naloxone‐induced morphine withdrawal syndrome was significantly suppressed by new synthetic 3,4,5‐trimethoxycinnamic acid derivatives (20 mg/kg/day). Most of 3,4,5‐trimethoxycinnamic acid derivatives were found to have high affinity to 5‐HT1A receptor. The naloxone‐induced morphine withdrawal syndrome was attenuated by (+)8‐OH‐DPAT (0.1 mg/kg/day, i.p.), a 5‐HT1A receptor agonist. In cortical neuronal cells, (+)8‐OH‐DPAT (1 μm) produced an elevation of the pERK 1/2 expression, and the elevated pERK levels were inhibited by WAY 100635, a 5‐HT1A receptor‐specific antagonist. Interestingly, the pERK levels were increased by the 3,4,5‐trimethoxycinnamic acid derivatives and the derivatives‐mediated changes in pERK levels were blocked by the WAY 100635. These results suggested that new synthetic 3,4,5‐trimethoxycinnamic acid derivatives have a potential antinarcotic effect through acting as a 5‐HT1A receptor agonist in mice.

  A ligand-free palladium-catalyzed carbonylation of vinyl iodides with arylboronic acids, permitting the synthesis of chalcones and α-branched enones, has been established. This reaction proceeds smoothly at ambient pressure and temperature, and works well even with a substoichiometric amount of base.
