  1-[4-(3-Phenylalkyl)phenyl]-2-aminopropanes as 5-HT_2A Partial Agonists

  摘要：

  Phenylalkylamines such as 1-(4-bromo-2,5-dimethoxyphenyl)-2-aminopropane (DOB; Pa) and its corresponding iodo derivative DOI (2) are commonly used 5-HT2 serotonin agonists. Previous studies have established that the 2,5-dimethoxy substitution pattern found in these compounds is optimal for high affinity at 5-HT2A receptors and that substituents at the 4-position can modulate affinity over a wide range. We have previously shown, however, that when the 4-position is substituted with a 3-phenylpropyl substituent (i.e., 3), the compound binds with an affinity comparable to that of Pa but that it possesses 5-HT2A antagonist character. The present study examined the structure-affinity relationships of 3, and the results were very much unexpected. That is, the 2,5-dimethoxy substitution pattern of 3 is not required for high affinity. Either of the two methoxy groups can be removed without untoward effect on affinity, and relocation of the methoxy substituents actually enhances affinity by as much as an order of magnitude. None of the compounds displayed more than 20-fold selectivity for 5-HT2A over 5-HT2C receptors. In addition, several were demonstrated to act as 5-HT2A partial agonists. As such, the results of this study suggest that the structure-affinity relationships of phenylalkylamines as 5-HT2A ligands now be reinvestigated in greater detail.

  the synthesis of alkynylphosphine oxides based on the oxidative alkynylation of secondary phosphine oxides with copper acetylides was developed. Activation with molecular oxygen in the presence of either a mixture of 1,2-dimethylimidazole and triethylamine or N-methylimidazole alone enabled the formal umpolung of the poorly nucleophilic copper acetylides, which were coupled with phosphine oxides under

  We report an efficient and sustainable electrochemical synthesis of copper(I) acetylides using simultaneous copper oxidation and Hofmann elimination of quaternary ammonium salts. The electrochemically-generated base was also regenerated electrochemically, making it catalytic. A ‘Click test’ (CuAAC reaction) was performed to assess product purity and an electrochemically-promoted, one-pot CuAAC reaction

  Two practical and complementary methods are reported for the synthesis of trifluoromethylated alkynes. The first one, a mix‐and‐stir process, is based on the oxidative trifluoromethylation of readily available and bench‐stable copper acetylides while the second one, which displays a broad substrate scope and has several advantages over existing procedures, is based on the oxidative copper‐catalyzed

  An original and user-friendly synthesis of alkynylphosphine-boranes, useful building blocks in organic synthesis, based on an oxidative P-alkynylation reaction with readily available copper acetylides is reported. The ability of a secondary phosphine protected with a borane to undergo oxidative coupling without oxidation of the P-moiety is demonstrated for the first time. The reaction, which proceeds at room temperature, is applicable to the preparation of enantioenriched and structurally complex alkynylphosphine-boranes.
