A series of indole cyclopropylmethylamines were found to be potent serotonin reuptake inhibitors. Nitrile substituents at the 5 and 7 positions of the indole ring gave high affinity for hSERT, and the preferred cyclopropane stereochemistry was determined to be (1S,2S)-trans. The cis-cyclopropanes had 20- to 30-fold less affinity than the trans, and the preferred cis stereochemistry was (1R,2S)-cis. Substitution of the indole N-1 position with methyl or ethyl groups gave a 10- to 30-fold decrease in affinity for hSERT, suggesting either a hydrogen-bonding interaction or limited steric tolerance in the region of the indole nitrogen. Compound (+)-12a demonstrated potent hSERT binding (K-i = 0.18 nM) in vitro and was more than 1000-fold less potent at hDAT, hNET, 5-HT1A, and 5-HT6. In vivo, (+)-12a produced robust, dose-dependent increases in extracellular serotonin in rat frontal cortex typical of a selective serotonin reuptake inhibitor. The maximal response produced by (+)-12a was similar to that of fluoxetine but at an approximately 10-fold lower dose.

A stable and recyclable Z-scheme g-C3N4/rGO/BiVO4 heterojunctionphotocatalyst was constructed by a facile two-step hydrothermal procedure. The photocatalyst was used for the synthesis of C-3 formylated indoles from indoles with methanol as an atom-economical formyl source for the first time, and 30% g-C3N4/rGO/BiVO4 exhibited superior photocatalytic efficiency. Quenching experiments showed that the
通过简便的两步水热法构建了一种稳定且可回收的 Z 型 gC 3 N 4 /rGO/BiVO 4异质结光催化剂。该光催化剂首次以甲醇为原子经济型甲酰源,以30% gC 3 N 4 / rGO/BiVO 4为原料,以吲哚为原料合成C-3甲酰化吲哚。表现出优异的光催化效率。猝灭实验表明,光生电子和空穴是实现反应的主要光活性物质。这种甲酰化反应具有优异的官能团耐受性、可重复使用的光催化剂和温和的反应条件等优点。克级合成表明了该策略在实际应用中的未来前景。
